A pоpulаtiоn оf 300 cаts hаs two alleles at some locus, F and f. In this population: 75 cats have genotype FF 200 cats have genotype Ff 25 cats have genotype ff A person uses the following reasoning to find the frequency of F. "75 cats have FF and 200 cats have Ff, so that makes 275 cats with F. There are 75 + 200 + 25 cats total, which makes 300. So the frequency of F is 275 / 300." They then divide 275/300 and report that as F's frequency. That is incorrect! What is wrong with their reasoning? Without actually doing the calculation, briefly explain how you'd find F.
