Law of Genetic Equilibrium Hardy-Weinberg law Explains how Mendelian segregation influences allelic and genotypic frequencies In a population
Explains how Mendelian segregation influences allelic and genotypic frequencies in a population. Law of Genetic Equilibrium Hardy-Weinberg law
Law of Genetic Equilibrium Hardy-Weinberg law Assumptions %o Large population 令 Random mating ☆ No natural selection No mutation 今 No migration If assumptions are met, population will be in genetic equilibrium
Law of Genetic Equilibrium Assumptions ❖ Large population ❖ Random mating ❖ No natural selection ❖ No mutation ❖ No migration If assumptions are met, population will be in genetic equilibrium. Hardy-Weinberg law
Law of Genetic Equilibrium Hardy-Weinberg law Allele frequencies do not change over generations. Genotypic frequencies will remain in the following proportions p+q=1 p2: frequency of AA P2+2pq+q2=13 2pq: frequency of Aa frequency of aa
➢ Allele frequencies do not change over generations. p＋q＝1 p 2＋2pq＋q 2＝1 p 2 : frequency of AA 2pq: frequency of Aa q 2 : frequency of aa Law of Genetic Equilibrium Hardy-Weinberg law ➢ Genotypic frequencies will remain in the following proportions:
Law of Genetic Equilibrium Hardy-Weinberg law Allele frequencies do not change over generations. Genotypic frequencies do not change over generations After only one generation of random mating, population will be in genetic equilibrium
Law of Genetic Equilibrium Hardy-Weinberg law ➢ Allele frequencies do not change over generations. ➢ Genotypic frequencies do not change over generations. ➢ After only one generation of random mating, population will be in genetic equilibrium
