Hardy–Weinberg principle

Observed heterozygosity is always _____ expected heterozygosity under inbreeding:

Less than reflects key principle in quiz on hardy–weinberg principle, where evolutionary mechanisms shape genetic variation and adaptation. In this context, Less than 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 Less than fits helps integrate natural selection, environment.

Inbreeding leads to

Inbreeding denotes mating between relatives sharing alleles identical by descent from common ancestor, increasing probability offspring receives same ancestral allele from both parents via two lineages. This elevates autozygosity, converting heterozygotes into homozygotes without altering allele frequencies in population. Inbreeding coefficient F quantifies fractional reduction in heterozygosity relative to random mating expectation, with genotype frequencies p squared plus pqF, two pq times one minus F, q squared plus pqF. Consequences include increased expression of recessive deleterious alleles and inbreeding depression affecting fitness.
