How to solve Population Genetics problems

The Hardy-Weinberg Equation To estimate the frequency of alleles in a population, we can use the Hardy-Weinberg equation. According to this equation: p = the frequency of the dominant allele (represented here by A) q = the frequency of the recessive allele (represented here by a) For a population in genetic equilibrium: p q = 1.0 (The sum of the frequencies of both alleles is 100%.) (p q)2 = 1 so p2 2pq q2 = 1 The three terms of this binomial expansion indicate the frequencies of the three genotypes: p2 = frequency of AA (homozygous dominant) 2pq = frequency of Aa (heterozygous) q2 = frequency of aa (homozygous recessive) #PopulationGeneticsFieldOfStudy #biology #hardyweinbergEquation #frequencyOfAlleles #recessive #dominant #binomialExpansion #homozygous #heterozygous #homozygousDominant #homozygousRecessive #NikolaysGeneticsLessons #hardyWeinbergAssumptions #hardyWeinberg #genetics #alleleFrequencies #genotypeFrequencies #hardyWeinbergEquations #hardyWeinbergEquilibriumExplained #hardyWeinbergPrinciple #amebaSisters #explanation #simplified #basics #overview #solving #population
