I need help pls...

Alina [70]

Answer:

Explanation:

The possible genotype of his father is $X^RY$ and $X^rY$ .

For sex-linked traits, an affected man always inherit the affected allele from the mother. The other chromosome, which is the Y chromosome is always from the father and this confers maleness on individuals.

The father of a man affected for a sex-linked trait can be affected for the same trait or otherwise. It does not have any bearing on the male child since the father only donates the Y chromosome to the male child.

Hence, in this case, the father can either be affected for the same trait ( $X^RY$ ) or be free from it ( $X^rY$ ).

The correct option is C.
