Which of the following are basic components of the Hardy-Weinberg model
A. Frequencies of two alleles in a gene pool before and after many random mating’s
B. Allele frequencies, number of individuals in the population
C. Allele frequencies in a subset of the population
D. Allele frequencies, phenotype frequencies
The correct answer is option A.
Frequencies of two alleles in a gene pool before and after many random mating’s are the basic components of the Hardy-Weinberg model.
It is because Hardy and Weinberg were trying to explore how and whether allele frequencies in a population change from one generation to the next.
The Hardy–Weinberg model:
H. Hardy and Wilhelm Weinberg have determined the Hardy–Weinberg model. It is also known as the Hardy–Weinberg equilibrium, theorem, or law. This model explains that “allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences”.
It includes mate choice, genetic drift, assortative mating, sexual selection, mutation natural selection, meiotic drive, gene flow, genetic hitchhiking, founder effect population bottleneck, and inbreeding.
There are five significant assumptions of Hardy-Weinberg assumptions which are the following:
- no mutation,
- random mating,
- no gene flow,
- infinite population size, and
- no selection.
If we assume these conditions, then there will be no migration, which means that so no alleles enter or leave the population. As there is No mutation, therefore allelic characteristics will not change.
