So, once again, to summarize, during gamete formation, the pair of alleles must separate, must segregate in accordance with the law of segregation, to form the sperm cells, the male gamuts and the XLS, the female gammates. Now, the sperm cell eventually combines with the XL in an arbitrary process. What that means is this combining with this is just as likely that this combines with this, or this combines with this, or this combines with this. And so each one of these possibilities is 25%. Now, in this particular case, because of the two types of individuals we combine all these offspring will look exactly the same. They have the same exact phenotype, and they will have the same exact genotype.
