A male inherits his X chromosome from his mother and his Y chromosome from his father. Therefore, he cannot inherit an X-linked recessive gene directly from his dad, as fathers pass their Y chromosome to their sons. If a male has an X-linked recessive condition, it must come from his mother, who can pass on the affected X chromosome. In summary, males inherit X-linked traits only from their mothers.

Who does a male inherit an autosomal recessive disorder from?
A male can inherit an autosomal recessive disorder from both of his carrier parents, who each pass down a copy of the mutated gene. This results in the male having two copies of the mutated gene, leading to the manifestation of the disorder.
If a daughter expresses an x-linked recessive gene she inherited the trait from?
If a daughter expresses an X-linked recessive gene, she inherited the trait from her father who carries the gene on his X chromosome. Since males only have one X chromosome, if they have the gene, daughters will always inherit it from their father.
What gene is a male gene called?
The gene that determines male biological traits is called the SRY gene, which is located on the Y chromosome. This gene plays a crucial role in the development of male sex characteristics during embryonic development.
Is the black male gene dominant over e white male gene?
Yes,
Is Red-green color blindness an X-linked recessive disorder?
Yes, red-green color blindness is typically an X-linked recessive disorder. This means that the gene responsible for red-green color blindness is located on the X chromosome, and individuals who inherit an abnormal gene on their X chromosome are more likely to express the trait if they are male, as they have only one X chromosome.
Who does a male inherit an autosomal recessive disorder from?
A male can inherit an autosomal recessive disorder from both of his carrier parents, who each pass down a copy of the mutated gene. This results in the male having two copies of the mutated gene, leading to the manifestation of the disorder.
What are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
If you mated a black female dog and a black male dog and one puppy came out yellow which color is the recessive gene?
In this case, yellow is the result of a recessive gene, as both parents were black. The yellow color must have been inherited from a common ancestor further back in the family line.
What makes a gene sex-linked?
The gene present on the sex chromosome either in recessive or dormant condition is called a sex linked gene. For example gene for color blindness present on X chrosome. It is carried by a female and mostly affect the male because male have XY type of chromosomal configuration.
What makes a gene sex linked?
The gene present on the sex chromosome either in recessive or dormant condition is called a sex linked gene. For example gene for color blindness present on X chrosome. It is carried by a female and mostly affect the male because male have XY type of chromosomal configuration.
If a daughter expresses an x-linked recessive gene she inherited the trait from?
If a daughter expresses an X-linked recessive gene, she inherited the trait from her father who carries the gene on his X chromosome. Since males only have one X chromosome, if they have the gene, daughters will always inherit it from their father.
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.
Under what condition is a single recessive allele expressed in a male?
A single recessive allele will be expressed in a male if he inherits that allele on his only X chromosome, as males have one X and one Y chromosome. This is because the presence of the recessive allele on the X chromosome has no dominant allele to mask its expression.
Could males be a carrier of a specific gene and not show traits?
Yes. It is possible for a male to carry a gene and not show it. However, it would have to be a recessive gene, therefore the trait would not show physically. Though, if it is a sex-linked gene, they would either show the trait or not. They cannot be carriers and not show it.
How often do you get a yellow puppie with a yellow male lab and a black female lab?
If the female carries the recessive gene necessary for yellow coloring, about 50% of the time. If she does not, never.
Does everyone have a recessive gene?
Yes. So do men. I believe it may be safe to say that any sexually reproducing individual will have at least some recessive genes. Women have 2 copys of the X chromosome, men have one copy of the Y chromosome and a single copy of the X chromosome. The Y chromosome contains much less information than the X chromosome. One of the genes on the Y chromosome is SRY this single gene prompts the body to develope into a male when the embyo is in the womb. In this case men have the gene and women don't have the gene, rather than women having a recessive copy of it. There are some XY women who have the SRY gene but lack a different gene which codes for the androgen receptors.
How is sickle cell anemia inherited?
This is inherited on the X chromoseome and is recessive. This means a female (who has XX chromosome pair) can only express the disease if she carries the trait on both chromosomes. This is because of the recessive nature of the gene. A male can only inherit the disease from his mother. This is he must have obtained his Y chromosome from his father so he obtains the X chromosome from his mother. A male cannot carry the gene without expressing it as he doesnt have another X chromosome to supress the recessive gene. ^ This answer is biologically incorrect because Sickle cell Anemia is actually autosomal recessive, not sex-linked recessive; this means that males and females are affected equally and it is NOT carried on the X chromosome. In order for the trait to show up in an individual, BOTH parents must be carriers of the disease (at least 1 sickle cell gene must be present).
