Answer:
if the man's genotype was Aa then the phenotype of their children would be: 50% albino and 50% normal skin pigmentation.
if the man's genotype was AA then the phenotype of their children would be: 100% normal skin pigmentation.
Explanation:
I almost completely doubt that the answer is the second one since the mom was albino then he has to have the trait in him some where and so his genotype would be Aa. However, I gave you both answers just in case but trust me if u choose one I suggest the first one (50% 50%) because it is the most accurate considering his mom was albino.
