Anth 246 To calculate the RMP, we must first calculate the combined probabilities, or the genotype frequency, at each locus. Recall that the calculations for heterozygous (2pq) and homozygous (p2) genotypes differ. What is the genotype frequency for D3S1358?

Explanation:

In population genetics, genotypic frequency is the frequency or proportion (that is, 0 <f <1) of genotypes in a population.

Thus it can be denoted:

{\ displaystyle f (\ mathbf {AA})} {\ displaystyle f (\ mathbf {AA})}

Compare with allelic frequency.

Hardy-Weinberg's law predicts genotypic frequencies from allelic frequencies under certain conditions, in which case:

{\ displaystyle f (\ mathbf {AA}) = p ^ {2}} {\ displaystyle f (\ mathbf {AA}) = p ^ {2}}

{\ displaystyle f (\ mathbf {Aa}) = 2pq} {\ displaystyle f (\ mathbf {Aa}) = 2pq}

{\ displaystyle f (\ mathbf {aa}) = q ^ {2}} {\ displaystyle f (\ mathbf {aa}) = q ^ {2}}

Genotypic frequencies can be represented by a De Finetti diagram.
