Father isn't colorblind mother is a carrier--one son is colorblind but the other is not how?
It is called x-linked alleles. It is rare for a female to have color blindness because the allele must be passed from both parents. Males only need one allele to be color blind.
With the equation, color blind female and non-color blind male reproduce. Each son has a 50% chance of developing the disorder.

What are the possible parental bloodtypes for a child with the blood-type A positive?
There are many possibilities, but two things are certain: at least one parent must be type A or AB, and at least one parent must be Rh + A child with blood type A+ can have the following combinations of parents: Mother A+, Father A+ Mother A+, Father A- Mother A-, Father A+ Mother A+, Father B+ Mother A+, Father B- Mother A-, Father B+ Mother A+, Father AB+ Mother A+, Father AB- Mother A-, Father AB+ Mother A+, Father O+ Mother A+, Father O- Mother A-, Father O+ Mother B+, Father A+ Mother B+, Father A- Mother B-, Father A+ Mother B+, Father AB+ Mother B+, Father AB- Mother B-, Father AB+ Mother AB+, Father A+ Mother AB+, Father A- Mother AB-, Father A+ Mother AB+, Father B+ Mother AB+, Father B- Mother AB-, Father B+ Mother AB+, Father AB+ Mother AB+, Father AB- Mother AB-, Father AB+ Mother AB+, Father O+ Mother AB+, Father O- Mother AB-, Father O+ Mother O+, Father A+ Mother O+, Father A- Mother O-, Father A+ Mother O+, Father AB+ Mother O+, Father AB- Mother O-, Father AB+
How much of your mothers genes do you receive and how much of your fathers?
Each human has 46 chromosomes. You get 23 from your mother and 23 from your father. Therefore, you have half (50 percent) from your mother and half (50 percent) from your father.
Is it true that the blood of a child comes from the sperm from the father and not the mother?
No. The child is a unique mix of both of its parents.
Is colorblindness a disability?
Not necessarily. The allele for colorblindness is recessive. For a female, in order to be colorblind she must have to recessive alleles for colorblindness. Example: XcXc would be colorblind. XCXc would be a carrier for colorblindness, but not colorblind. For a male, because colorblindness is a sex-linked gene, he only needs one allele to be colorblind. Example: XcY is colorblind. XCY is not colorblind.
In a punnet square where the mothers genotype is Dd and the fathers genotype is dd does the mother or the father have dimples?
In this case, the mother does not have dimples (Dd) but the father does not have dimples (dd). The Punnett square would show that half of the offspring would have dimples (Dd) and the other half would not have dimples (dd).
Why cant women be color blind?
Women can be colour blind.AnswerI am a woman who is red--green colorblind. The trait is carried on the X chromosome. Males receive an X chromosome from their mother and a Y from their father. If the X carries the trait of colorblindness, the male will be colorblind. Females need to receive two defective X chromosomes to be colorblind, one from their father and one from their mother. If a women has only one defective X chromosome, she will be a carrier of the trait. My father was red-green colorblind and so was my mother's father, making my mother a carrier of the trait, although she is not colorblind herself. I have two sisters who are not colorblind, as they each received a non-defective X chromosome from my mother. I knew before my son was born that he would be red-green colorblind, as the X chromosome he received from me carried the trait.
What would be the color vision of children if their mom is colorblind and their dad is normal?
Colorblindness is a recessive, sex-linked trait, and the gene that causes it occurs on the X chromosome. For the mother to be colorblind, she must have two copies of the gene and be homozygous recessive. The father, on the other hand, can not have the gene, because he (as a male) only has one X chromosome. So, if we let Xc represent the recessive gene for colorblindness and Xn represent the normal gene, the the mother is XcXc and the father is XnY. All of their children will receive the recessive gene from their mother. In the males, this means that they will be colorblind, because the chromosome they get from their father will by the Y chromosome. The daughters, however, will get the Xn gene, which is dominant and will override the gene for colorblindness. Thus, all of the couple's sons will be colorblind, and none of their daughters will be.
Are huskys colorblind?
Yes,therefor they are colorblind like all other dogs.
Can women go colour blind?
AnswerColor blindness is the inability to differentiate between different colors. The most common type is red-green color blindness. This occurs in 8 percent of males and 0.4 percent of females. It occurs when either the red or green cones are not present or not functioning properly. People with this problem are not completely unable to see red or green, but often confuse the two colors. This is an inherited disorder and affects men more commonly since the capacity for color vision is located on the X chromosome. (Women have two X chromosomes, so the probability of inheriting at least one X with normal color vision is high; men have only one X chromosome to work with. The inability to see any color, or seeing only in different shades of gray, is very rare.AnswerWomen can be color blind, but only if their father is. If they got a carrier gene from their color blind father and one from their mother, they would be homozygous recessive, and therefore would be colorblind. Actually I am a woman and my dad is color blind and I am not.The answer says a woman can be color blind only if her father is. In your case, you had a chance of being color blind because your dad is.Another answerNot all women who are color blind has their father color blind. I - being female, I am partially color blind and cannot tell what different color shades are sometimes. Meaning I when dark purple is put in front of me I see light purple. Or if red is in front of me, I see pink. Vice versa, and same with other colors. My father is not color blind. I am not sure that this is color blindness that you have. It seems that you have a color vision defect called Protanomaly, where your color deficiency has to deal with saturation. When someone is color blind it has to deal with hue of the color. This form of color deficiency is also rare.AnswerColor blindness is yummy X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. Since women have two X chromosomes, both must be affected in order for her to be colorblind. A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy). Thus, her father must be colorblind, and her mother must be a carrier (or colorblind), and she must receive a copy of the affected chromosome. For the female offspring to be color blind, the father must be color blind. A father with normal vision would produce heterozygous female offspring and they would be a carrier.AnswerOK girls can not get colorblind only guys have the chromosome gene because the women gives the X and the guy determines if it a boy or girl the colorblind is in the Y chromosome if you get that one your a guy i know this my mom works at a hospital girls can not become colorblind._ok im not the one who posted this but i am here to say that's bull crap my mom is fully color blind and can only see black white and shades of gray like those old movies. its do to a mutation of cells in there eyes that kicks out color conesAnswerI just got done studying genetics and yes it is VERY RARE but women can be colorblind. If a female gets a bad X-chromosome from mom then she is a carrier and can pass it to her son but if she gets a bad one from her mom then her dad would have to have a bad one for her to be colorblind, which is what makes it rare that she would get a bad one from her mother and her dad would be colorblind. She could just get the bad one from dad if he is colorblind but a good one from mom and still be just a carrier.AnswerI am a woman who is red--green colorblind.

What is it called when my father's mother and my mother's mother are sisters?
When your mother's mother and your father's mother are sisters, then your mother and father are first cousins to each other.
What is your relationship to your mother and father if your mother and father are 2 cousins?
Uh, they're your mother and father. Their relationship to each other does not change their relationship to you. Your parents are your parents regardless.

What is your mother or father?
Your grandfather is going to be the parent of your father or your mother. Most people have two grandfathers. In families where there has been divorce, there could be multiple individuals referred to as grandfather.
Can a colorblind father and normal sighted homozygous mother produce a daughter that is a carrier?
Color blindness is an X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy). So, If a woman is a carrier, Xx, and a man is normal, XY, they have several different chances for different offspring: XX (a normal girl) XY (a normal boy) Xx (a normal girl who carries the colorblindness gene) xY (a colorblind boy) The short answer is, that if a woman has a boy, he has a 50% chance of being colorblind.
Why can only females be carriers of sex-linked genetics disorders?
This is not an entirely accurate statement, but it is generally true. It happens because sex-linked genes are located on the X chromosome only. Males have only one X chromosome (XY) and the corresponding Y chromosome from their fathers do not have genes for sex-linked traits, including color vision and proper blood clotting. If a mother has normal color vision but carries a gene for color blindness on her other X chromosome, her genotype is Cc. If she has a daughter and that daughter inherits her mother's recessive gene, it is usually balanced by her father's X chromosome if he has normal color vision, and the daughter would be Cc like her mother. However, although they are rare, a colorblind female is possible if her mother is a carrier (or is color blind, cc) and her father is colorblind also. However, a son only inherits one X chromosome, so he is totally dependent on which X chromosome his mother gives him. His father's Y chromosome, which makes him male, does not have this gene on it. The son has a 50-50 chance of inheriting his mother's color blind gene, and if he does, he will be colorblind based on the gene inherited from his female parent. His male parent donated a Y chromosome, which has no genes for this trait on it, so the mother alone determines this trait in her sons.
What are the chances of a male with normal vision and a color-blind female having a color blind son?
Color blindness is an X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind. A woman will carry the colorblindness gene if: a. Her father is colorblind b. Her offpsring are colorblind She may carry the colorblindness gene if: a. Male family members (brothers, uncles, etc.) are colorblind A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy) So, If a woman has normal vision (assuming she does not have a family history of colorblindness), XX, and a man is colorblind, xY, they have several different chances for different offspring: Xx (a normal girl who carries the colorblindness gene) XY (a normal boy) Xx (a normal girl who carries the colorblindness gene) XY (a normal boy) The short answer is that ALL CHILDREN WILL HAVE NORMAL VISION. However, all daughters will be CARRIERS, meaning they can pass colorblindness on to their children.
What relationship is your mothers aunt to you?
Your aunt is the sister of your mother or father, so her mother is your grandmother. On the other hand, your aunt may also be the wife of the brother of your mother or father. Then her mother is not related to you.
