WebThe more genetic variation that exists in a population, the greater the opportunity for evolution to occur. As the number of gene loci that are variable increases and as the number of alleles at each locus becomes greater, the likelihood grows that some alleles will change in frequency at the expense of their alternates.

WebDec 5, 2024 · In this case, (20.2.4) s = 1 − 0.8 = 0.2. The change in frequency of the dominant allele ( Δ p) after one generation is expressed by the equation. (20.2.5) Δ p = s p 0 q 0 2 1 − s q 0 2. where p 0 and q 0 are the initial frequencies of the dominant and recessive alleles respectively. Substituting, we get. WebSince evolution is change in the genetic makeup of a population over time, a general approach to modeling this is to determine the allele and genotype frequencies in the next generation (p t+1) that result from the action of a force on those frequencies in the current generation (p t). Thus : p t-> evolution happens -> p t+1
