What are the 5 ways a population can evolve?

Answer 1

A population will most likely evolve when there is a small population, mutations exists, natural selection may take place, nonrandom mating occurs, and/or gene flow may occur.

Sexual selection, genetic drift, Gene flow, Mutation, and natural selection are five ways a population can evolve.

Sexual selection is natural selection arising through preference by one sex for certain characteristics in individuals of the other sex.

Genetic drift is variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

Gene flow is the transfer of alleles or genes from one population to another.

Mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.

Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
