ANTH 1810 Lecture Notes - Lecture 12: Population Genetics, Genetic Drift, Species Problem
Document Summary
Pleotropic link between white fur and blue eye cat. Does not cross over, align or recombine. Mitochondria has their own dna- which is mtdna. Mitochondria are just clones of each other. 1930s- darwin meets mendel: how natural selection acts on variation (differential reproductive success, how variation is inherited. Bioevo- change in allele frequencies in a population from one generation to the next. Bioevo- unit- allele frequencies in a population- can be geographic- related to culture- and language. Unit- 1 generation to the next- 30 years for humans, 1-2 years for dogs, 10 years for apes. Gene pool- all the alleles in a deme. Gene pool- all the genetic information in a breeding population. Biological species concept- group of animals that produce fertile offspring. Environment is changing- globe is warming- polar bears are moving south: grizzly bears are moving north. Comparative anatomy- phenotypes as a proxy for genotypes: variation in pheno= variation in gene.
