How is organism related to population
WebPopulation genetics is the study of genetic variation within and among populations and the evolutionary factors that explain this variation. Its foundation is the Hardy - Weinberg law, which is maintained as long as population size is large, mating is at random, and mutation, selection and migration are negligible. WebTwo important factors are large population size (making it more likely that some individuals in the population will, by random chance, have mutations that provide resistance) and short lifecycle. Bacteria and viruses, which …

WebIn genetics, a population is often defined as a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring, and such a breeding group is also known therefore as a gamodeme.
