WebKey Points Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population. Fitness is a measure … WebAug 28, 2024 · Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

WebGenetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations. Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100\% 100% frequency, of other alleles. properties of complex numberWebThe diversity of alleles and genotypes within a population is called genetic variance.
