Unformatted text preview: frequency of the alleles in the population Negative (inverse) frequency dependence When rare, it’s favored: when common it is disfavored Benefits to being rare In populations, genetic variation will be maintained. ∆p will increase if the allele is rare ∆p will decrease if the allele is common This must create a sinusoidal curve that will at one point cross zero in the change in fitness- that point is p hat Positive frequency dependence When rare, it’s disfavored When common, it’s favored Benefits to fitting in Eliminates variation; fixes the more common allele Ther...
