The five Hardy-Weinberg principles for non-evolving populations are extremely large population size, no gene flow, no mutations, random mating, and no natural selection. An extremely large population size is necessary because the smaller the population, the greater the role chance fluctuations play in allele frequencies from generation to generation. It is important that there is no gene flow because that transfer of alleles between populations can alter allele frequencies. Similarly, mutations modify the gene pool by introducing/removing genes from chromosomes or by changing one allele into another. Random mating is important so that individuals do not preferentially choose certain genotypes in their mates. Also, there must be no natural selection because if individuals carrying different genotypes had different survival and reproductive success, then that would alter the allele frequencies.
No statements, but a few of the Hardy-Weinberg conditions. Random mating. No gene flow. No natural selection.
Any violation of the conditions necessary for Hardy-Weinberg equilibrium can result in changes in allele frequencies in a population. This includes factors such as mutation, gene flow, genetic drift, non-random mating, and natural selection that can disrupt the genetic equilibrium established by Hardy-Weinberg principles.

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.
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.

One condition for Hardy-Weinberg equilibrium is a large population size, to prevent genetic drift from causing allele frequency changes.
The Hardy-Weinberg equilibrium does not directly impact the inheritance patterns of X-linked recessive traits. Hardy-Weinberg equilibrium is a principle that describes the genetic makeup of a population when certain conditions are met, while X-linked recessive traits follow specific inheritance patterns based on the X chromosome.

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