Phenotypes frequencies in a population vary over time.  Phenotypes are determined by genotypes which are determined by  combinations of alleles. If a population is in Hardy- â¦ Weinberg  Equilibrium the allele frequencies will remain constant.Even  though the frequency of each allele remains constant, the way that  the alleles are paired in individuals will vary, changing the  phenotype frequency in each generation.f a population is in Hardy- â¦ Weinberg  Equilibrium the allele frequencies will remain constant.

Definition. It describes the phenomenon of differing clinical features or phenotype among individuals carrying the same gene allele or genotype. Expressivity differs from penetrance, which describes the probability that a genetic variation (or allele) will yield the phenotype at all.Variable expression of a phenotype may be influenced by other genetic variations, epigenetic factors, or environment.This term is often used in conjunction with explanations of variable severity of autism-related traits within families.efinition.
