Incomplete dominance is a form of inheritance where the heterozygote exhibits an intermediate phenotype between the two homozygous forms. Unlike complete dominance, neither allele is fully dominant, and both contribute to the resulting phenotype. This phenomenon provides an important example of how genetic interactions can result in a blending of […]
Population genetics is the study of the genetic composition of populations and how it changes over time due to evolutionary processes such as mutation, natural selection, genetic drift, and gene flow. It combines principles from genetics, statistics, and evolutionary biology to understand how alleles are distributed in populations and how […]
Hardy-Weinberg equilibrium is a principle that describes the genetic composition of a population when allele and genotype frequencies remain constant from generation to generation, provided that certain conditions such as random mating, no selection, no mutation, large population size, and no gene flow are met. It serves as a null […]
Gene Mutation refers to a permanent alteration in the DNA sequence that makes up a gene. Mutations can occur due to various factors, including environmental influences, errors during DNA replication, or the action of mutagens. They can lead to changes in the protein produced by the gene, potentially affecting an […]
Epistasis is the phenomenon where the expression of one gene is affected by one or more other genes. This interaction can modify or completely mask the phenotypic effects of alleles at another locus. Epistasis is a key aspect of genetic regulation and plays a role in complex traits and disease […]
