Answered by Examlex AI CopilotThe equation for the Hardy-Weinberg theory of genetic equilibrium is:
p^2 + 2pq + q^2 = 1
Where:
- p^2 represents the frequency of the homozygous dominant genotype
- 2pq represents the frequency of the heterozygous genotype
- q^2 represents the frequency of the homozygous recessive genotype
- 1 represents the total frequency of all genotypes in the population
The five assumptions that must be met in an idealized population at equilibrium are:
1. Large population size: The population must be large enough to minimize the effects of genetic drift.
2. Random mating: Mating within the population must be random, with no preference for specific genotypes.
3. No migration: There should be no migration of individuals into or out of the population, which could introduce new alleles.
4. No mutation: The genetic makeup of the population should remain constant, with no new mutations occurring.
5. No natural selection: All genotypes must have equal fitness and there should be no selective pressure favoring one genotype over another.
