The answer would be "Father's father" 'cause when boy born, he receives Y chromosome from his father and not X so he can't transfer it to his daughter, as he will transfer his X chromosome to her.
In short, Your Answer would be Option D
Hope this helps!
Hey there! :D
When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".
I hope this helps!
