Answer:
C
Explanation:
<em>The possible genotype of his father is </em><em> and </em>
<em>.</em>
<u>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.</u>
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 () or be free from it (
).
The correct option is C.
