Gene Flow

Gene flow, also known as gene migration, is the introduction of genetic material from a particular population to another population of the same species through interbreeding. For example, a bee facilitates its reproductive process by carrying pollen from…

Population Biology

Population biology is the study of patterns in organism populations, specifically the growth and management of population size, population genetics, the evolution of life history, species interactions, and demography.

Speciation

The process of speciation involves the formation of new species during evolution. The new species evolve in such a way that both new and old species are not able to interbreed. Thus, speciation occurs when few members of one species get separated from th…

Allele Fixation

A gene is a unit of heredity and contains both physical and functional information that shapes an individual. Genes are made up of DNA (deoxyribonucleic acid), which carry genetic information from one generation to another, from one set of parents to the…

Describe the characteristics of a population that is in Hardy–Weinberg equilibrium.

Solution Summary: The author explains the Hardy-Weinberg principle, which states that the allelic frequencies of the gene remain constant from one generation to another when the evolutionary influences are absent.
