Hardy-Weinberg equation

If p=0.8, frequency of homozygous dominant is:

0.64 reflects key principle in quiz on section e- hardy-weinberg equation pyqs solved, where evolutionary mechanisms shape genetic variation and adaptation. In this context, 0.64 aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why 0.64 fits helps integrate natural selection, environment.

The frequency of homozygous dominant genotype is represented by

Hardy-Weinberg partitions allele frequencies p and q into genotype classes after random gamete union. Homozygous dominant AA requires receipt of A allele from both sperm and egg, probability p multiplied by p equals p squared. Similarly recessive homozygote aa is q squared and heterozygote is two pq, summing to one for total population. Symbol p alone denotes allele frequency, not genotype frequency, while two pq denotes heterozygotes. Therefore representation of dominant homozygote relies on squaring allele frequency, cornerstone for predicting dominant trait prevalence and for inferring allele frequencies from dominant phenotypes.
