How does allele frequency change between generations
rarely
No statements, but a few of the Hardy-Weinberg conditions. Random mating. No gene flow. No natural selection.
For a population to be in Hardy-Weinberg equilibrium, it must meet several key requirements: there must be no mutations, no gene flow (migration), random mating, a large population size to minimize genetic drift, and no natural selection affecting the alleles in question. These conditions ensure that allele frequencies remain constant across generations, allowing for the prediction of genotype frequencies based on the Hardy-Weinberg principle.
the phenotype frequency does not change
Mutations introduce new genetic variation into a population, which can disrupt the balance of allele frequencies required for the Hardy-Weinberg equilibrium. If a mutation increases the frequency of a particular allele, it can lead to deviations from the expected genotype frequencies under the Hardy-Weinberg equilibrium.

Hardy and Weinberg aimed to understand the genetic variation in populations and how allele frequencies remain stable over generations in the absence of evolutionary influences. Their work led to the formulation of the Hardy-Weinberg principle, which describes the conditions under which allele and genotype frequencies in a population will remain constant, allowing for predictions about trait inheritance and population genetics. This principle underscores the importance of factors like mutation, selection, and genetic drift in altering trait frequencies.

Hardy-Weinberg equilibrium
If a new allele appears in a population, the Hardy-Weinberg formula cannot be used. This is because there is now no equilibrium.
To solve Hardy-Weinberg problems effectively, you need to understand the formula and assumptions of the Hardy-Weinberg equilibrium. Calculate allele frequencies, use the formula to find genotype frequencies, and compare them to the expected frequencies. Repeat for each allele and genotype.
To determine how allele frequency changes
Some common strategies for solving Hardy-Weinberg problems efficiently include using the Hardy-Weinberg equation, understanding the assumptions of the Hardy-Weinberg equilibrium, and knowing how to calculate allele frequencies and genotype frequencies. Additionally, using Punnett squares and understanding the concept of genetic drift can also help in finding answers quickly.
