What is the probability of color blindness if the father is color blind and the mother carries the trait?
All daughters are normal, half the sons are color blind.
The above answer is incorrect. Half of the daughters are color blind and half of the sons are color blind. Since the father always donates color blindness, it is up to the mother in each case (in the son's case, the father is irrelevant) to determine if the child is color blind or not. Since she is a carrier, the chance is 50-50.
What else can I help you with?
Which parental pair could produce female with color blindness?
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
A mother has one allele for color blindness and one allele for normal vision. What is the probability that her gamete will have the allele for color blindnessg?
50% (apex)
What is the risk of a colour blind child in a family when father is colour blind and mother is normal?
if the child is a boy, 0%. if it's a girl, either 100% if the trait is dominant in the father or 50% if it is recessive. there is also the possibilty of the daughter having it but just being a carrier (has the disease but no signs of it)
Why do you think humans have two sets of 23 chromosomes?
Bcoz one chromosome comes from mother which is always X chromosome carries characteristics from mother and the second chromosome comes from father that may be X or Y, which carries characters from father.
Why could a girl with Turner's syndrome have red-green color blindness even though both of her parents have normal vision?
Turner's syndrome is caused by a missing or incomplete X chromosome. Since the gene for red-green color blindness is located on the X chromosome, if the girl inherited the X chromosome carrying the red-green color blindness gene from her father, she could have the condition even though her father has normal vision. Her mother would be a carrier of the gene, but with two X chromosomes, she likely does not exhibit red-green color blindness herself.
A color blind son inherited this trait from?
his mother because color blindness is a sex-linked trait that is found on the X chromosome, which is inherited from the mother, as opposed to the Y chromosome, which is inherited from the father. So a male can only inherit the gene for color blindness from his mom.
A mother has one allele for color blindness and one Allele or normal vision what is the probability that her Gamete Will have the Allele for the color blindness?
50%
What was the chance that the child will be color blind?
The probability of a child being color blind depends on the parents' genetic makeup. If the mother is a carrier of the color blindness gene located on the X chromosome and the father does not carry the gene, the chances are 0% for a daughter and 50% for a son to inherit color blindness. If the father is color blind and the mother is a carrier, the chances are 50% for a daughter and 50% for a son to inherit color blindness.
Which parental pair could produce female with color blindness?
X' = color blindnessX'X'-- X --X'Yis a cross that could lead to a color blind female as the mother is homozygous recessive and the father's X chromosome is the recessive color blind trait.
Why is it impossible for a father to pass down red green color blindness to his son?
Boys have one X and one Y chromosome. Color blindness is found on the X chromosomes. Since boys will always get their X chromosome from their mother and their Y chromosome from their father, father's can never pass on red/green color blindness to their son's. However, since father's do pass their X chromosome to their daughters, they can pass on the trait to their daughters. In this case, daughters have two X chromosomes (one from their mother and one from their father), so they will NOT have red/green color blindness unless they received the defective gene from their mother AND their father. This is the reason that color blindness is 9 times more common in boys than girls.
Why is a son who receives the allele for color blindness from his mother always colorblind?
Color blindness is a sex-linked trait that is carried on the X chromosome. Since males inherit their single X chromosome from their mother, if the mother carries the allele for color blindness, her son will inherit it and be colorblind. Females need two copies of the allele to be colorblind, so they can be carriers without exhibiting the trait.
A mother has one allele for color blindness and one allele for normal vision. What is the probability that her gamete will have the allele for color blindnessg?
50% (apex)
What will be the child's blood group if mother is A plus and Father A plus?
A positive with highest probability
What is the probability of getting curly hair?
The probability of getting curly hair depends on whether your parents do or not. Hair genes are decided by the mother. So, if the mother has curly hair, more than likely the offspring will as well. If the father has curly hair and the mother does not, the probability is considerably lowered.
Probability of son blood group being B if mother is A and father is AB?
25% to be B.
Which parent regardless of the phenotype is responsible for color blindness in a son?
Color blindness is typically inherited in an X-linked recessive pattern. This means that a son inherits his X chromosome from his mother and his Y chromosome from his father. Therefore, regardless of the mother's phenotype, she is the parent responsible for passing on the X chromosome that may carry the gene for color blindness, while the father contributes a Y chromosome. If the mother is a carrier or affected, there is a chance for the son to be color blind.
If a mom colorblind and the father not colorblind what is the probability the child will be colorblind?
If the mother is a carrier of the colorblind gene (XcX) and the father has normal color vision, the probability of their child being colorblind is 50%. This is because the child has a 50% chance of inheriting the Xc chromosome from the mother and developing colorblindness.
