Then p = 0.5 (and 0.5). So $f(AA)+F(Aa) = 0.5^2+2*0.5*0.5 = 0.75$ or 75%. It doesn't matter whether you are looking at the gene from mom or dad side since the frequency of the allele is known at a population level so its assumed that both the egg and sperm have the same chance of having that specific gene/allele.

I feel bad if I were to take away Martin's checkmark and give it to you :p, but this answer covers everything I wanted to know. I really appreciate the time you took to write this out! Nov 6 comment Cardinality of Vitali sets: countably or uncountably infinite? Yup I realize that :), i'm just a bit pedantic on this stuff. even though it doesn't matter to the final result.. Thanks for your response though! Nov 6 accepted Cardinality of Vitali sets: countably or uncountably infinite? Nov 6 comment Cardinality of Vitali sets: countably or uncountably infinite? Thank you for the good response! I was getting confused because I was looking at a proof where they were referring to disjoint vitali sets and how those were countable. But I realize that in the general case, of any random vitali set, there are uncountably many. I gave Martin the checkmark because it was a bit clearer for me and he answered first, but yours was good too! Nov 6 comment Cardinality of Vitali sets: countably or uncountably infinite? @StevenStadnicki that actually solved the root of the problem! I was looking at the proof of why the vitali sets are non-measurable where they basically had a vitali set, then created new vitali sets by shifting the original set by a rational number and then performed the "union of a countable number of disjoint sets" to prove that this should add up to a length of 1 but instead is either 0 or infinity. So I was under the impression that there was a countable infinite number of vitali sets. And you made me realize that this is only true if they are disjoint vitali sets
