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.
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.
Allele frequency is stable
No disruptive circumstances must be present in random mating in a population for Hardy-Weinberg equilibrium to occur. Mating must happen randomly. No allele can give an advantage
No, sexual selection is not a requirement for Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium describes a population in which allele frequencies remain constant over generations, given certain criteria are met. Sexual selection, on the other hand, refers to the differential reproductive success based on traits that are attractive to potential mates.

Hardy-Weinberg equilibrium
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.
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.
One condition for Hardy-Weinberg equilibrium is a large population size, to prevent genetic drift from causing allele frequency changes.

When the Hardy-Weinberg equilibrium is achieved, it indicates that a population's allele and genotype frequencies remain constant over generations, suggesting that no evolutionary forces are acting on the population. This equilibrium assumes conditions such as random mating, no natural selection, no mutations, large population size, and no gene flow. If any of these conditions are violated, evolution occurs, leading to changes in allele frequencies over time. Thus, the Hardy-Weinberg equilibrium serves as a baseline to identify evolutionary processes at work.
