Génétique des populations
Qu'est-ce que la génétique des populations ?
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, ...
Principe de Hardy-Weinberg
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the ...
Mutation, flux génétique et dérive génétique
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions ...
Dérive génétique
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and ...
Flux génétique
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
