Explore the concepts of genetic equilibrium and drift in evolution, where the gene pool's allele numbers remain stable over time or change due to random events. Learn with examples and definitions in the field of population genetics.
E N D
gene pool • all of the alleles of a population
genetic equilibrium • when the number of alleles in a population remains the same over generations. Example: 150 years ago, there were 70 alleles for seeded watermelons, and 30 alleles for seedless watermelons. Now, there are still 70 alleles for seeded watermelons and 30 alleles for seedless watermelons.
genetic drift • when the number of alleles in a population is changed by a random event. or
