MICHAEL IS COLOR BLIND! Whose genes caused this to happen

[From: ] [author: ] [Date: 11-09-24] [Hit: ]
and their father must be color blind for this to occur.If Michael is a normal boy (no polyX/Y or anything like that), he has to receive the Y chromosome from his father and the X chromosome from his mother. If he is colorblind, the X must contain the gene that leads to colorblindness.-Edgar doesnt know what hes talking about.......
Please source the answer you give or a good reason for the answer, not just guess letters. THANK YOU! :P

a. Only his father’s genes
b. Only his mother’s genes
c. Either of his parents’ genes could have caused this
d. Neither parent’s genes, as color blindness is not inherited

(b). The most common type of genetic colorblindness is the result of a faulty allele on the X chromosome. Since Michael inherited his X chromosome from his mother, the answer is (b). He inherited the Y chromosome from his father; it has no alleles for color vision. If he had inherited an X chromosome from his father, he'd be a daughter, not a son.

B

The color blind gene is X-linked recessive.
Men are more likely to be color blind since they only have one X chromosome.
Women must have two recessive copies of the X chromosome to be color blind, and their father must be color blind for this to occur.

If Michael is a "normal" boy (no polyX/Y or anything like that), he has to receive the Y chromosome from his father and the X chromosome from his mother. If he is colorblind, the X must contain the gene that leads to colorblindness.

Edgar doesn't know what he's talking about.

The answer is B: Only his mother's genes.

The gene for colorblindness is on the X chromosome. You'll recall that men have one X and one Y chromosome, and women have two X chromosomes. When they have a baby, the woman always gives one of her X chromosomes; if the father gives his X, then the baby is a girl. If he gives his Y, then the baby is a boy.

Since MICHAEL, a male, is colorblind, his father gave him a Y chromosome. Colorblindness is on the X chromosome though, which he MUST have gotten from his mother. Therefore, his mother's genes are responsible for his colorblindness.

B

Father contributes the Y chromosome, and the mutation is X-linked. Lack of the second X chromosome prevents compensation for the mutation responsible for micheal's colour blindness.

If michael was a girl, then both of the X chromosomes (ie father n mother's) have to be mutated.

b his mother's genes

Assuming Michael is a traditional male with XY chromosome combination...He received the X from his mother and Y from his father. Colorblindness mutations are traditionally associated with X chromosome mutations. Males are far more likely to have colorblindness because they only have 1 X chromosome and no spare copy of the gene to use if one is mutated like females do.

-
The color blind gene comes from the father only sense the males ability to see colors is less sophisticated than the female
