ANTH 1001 Chapter : Chapter 4 Genes And Their Evolution Population Genetics
Document Summary
Chapter 4: genes and their evolution population genetics: alleles in population, individuals do not evolve, it is a species or population that evolve, phenotype frequency. Mutations create new alleles, making new phenotypes possible. (only source of new variation: they are random. 2 special cases: genetic bottlenecks and founders effect: it is high in small populations. 2: founder effect- loss of genetic variation when a new colony is established (anthropology class cult living on indian mounds. A local population of organisms that have similar genes, interbreed, and produce offspring. (page 86) All the genetic information in the breeding population. (page 86) Any circumstance that prevents two populations from interbreeding and exchanging genetic material, such as when two populations are separated by a large body of water or a major mountain range. (page 86) Small-scale evolution, such as changes in allele frequency, that occurs from one generation to the next. (page 88)
