ANP 206 Lecture Notes - Lecture 3: Allele Frequency, Population Genetics, Genetic Drift
Document Summary
Group of organisms that choose mates within the same group. Definition is not perfect it doesn"t describe human reality. Genotype : the genetic constitution of an individual organism. Genotype frequency: measure of relative proportions alleles within a population. Changes in allele frequency within population drives evolution. Measure of relative proportion of alleles within a population. Mathematical statement in the absence of non random mating and evolutionary forces, genotype and allele frequencies will remain the same from one generation to the next. Concluded that gene pools are stable but taking into considered evolution should be expected in all populations equation : p + q = 1 , p^2+2pq+q^2=1 p=individuals that are homozygous dominant q=individuals that are homozygous recessive. Punnett squares used to predict probability of offspring genotypes for particular traits based on the known parental genotypes. Responsible for introducing new alleles to the population. Fitness : an organism"s probability of survival or reproduction.
