WebApr 9, 2024 · Here we go! You just solved why f A A = p 2. You can apply the exact same logic to find out f B B = q 2. Now the probability to first draw a A allele and then a B allele is p q. Therefore, f A B = p q. The probability to first draw a B allele and then a A allele is q p = p q as well. Therefore, f B A = p q.
