__Population Genetics__


 * Hardy Weinberg Model**
 * ideal mathematical model of a gene pool with many assumptions
 * ASSUMPTIONS:
 * 1) Organisms are Diploid
 * 2) No Generation Overlap
 * 3) Large Population
 * 4) Mutation/Migration are Negligible
 * 5) Sexual Reproduction Occurs
 * 6) Random Mating
 * 7) No Natural Selection
 * Mathematical Statement: p²+2pq+q²=1
 * p = frequency of Dominant Allele
 * q = frequency of Recessive Allele
 * p+q=1 (frequencies of all alleles=1 or 100%)
 * p² = frequency of AA homozygous dominant
 * q² = frequency of aa homozygous recessive
 * 2pq = frequency of Aa heterozygous
 * Why is the Hardy-Weinberg model useful?
 * fits real world data, despite many assumptions
 * shows genetic variation tends to remain in populations
 * can detect whether a population is evolving or staying at equilibrium
