To determine how allele frequency changes
How does allele frequency change between generations?~
D, how does allele frequency change between generations? Apex
Hardy-Weinberg equilibrium
The Hardy-Weinberg equation is as follows: p2 + 2pq + q2 = 1 p & q represent the frequencies for each allele.
Allele frequency is inherently stable.
allele frequency
One big Hardy-Weinberg assumption is that there is no mutation taking place in the population of interest. Mutation and selection lead to evolution, which the Hardy-Weinberg assumption also does not allow in a population. So, if there is the variation brought about by mutation then there is a chance of natural selection happening and this violates Hardy-Weinberg assumptions.
How does allele frequency change between generations
Hardy and Weinberg wanted to answer the question of how genetic variation is maintained in a population over time. They developed the Hardy-Weinberg equilibrium principle, which describes the expected frequencies of alleles in a population that is not undergoing any evolutionary changes.

No statements, but a few of the Hardy-Weinberg conditions. Random mating. No gene flow. No natural selection.

If a new allele appears in a population, the Hardy-Weinberg formula cannot be used. This is because there is now no equilibrium.
