Unformatted text preview: example, p for a given population of humans is the probability of finding allele A by selecting an individual from that population at random and then selecting one of their two alleles at random. Since p and q are probabilities and in this example there are only two possible alleles; p + q = 1 Correspondingly, there are three possible genotype frequencies : f( A /A ) + f( A /a ) + f( a /a ) = 1 We usually can't get allele frequencies directly but must derive them from the frequencies of the different genotypes that are present in a population p = f( A /A ) + 1 /2 f( A /a ) (homozygote) (heterozygote) q = f( a /a ) + 1 /2 f( A /a )...
