Document Summary
Doesn"t matter which type of allele is more frequent (e. g. dominant or punnet squares recessive: can we predict genotype and phenotype frequencies family level inheritance method does not work. Ww: gene pool = all alleles present in the population, allele frequencies give expected offspring genotype frequencies based on probability, genotype frequencies of offspring, pxp = p2 a1a1, 2 ( p x q) = 2pq a1a2 (multiplied by 2 because there is two ways to get it, q x q = q2, where, London, how many of the 350, 000 would carry this allele: let dominant allele be a, and the recessive be a, dead individuals are homozygous recessive (aa, a heterozygote is a carrier (they have the gene, but don"t express it, we are looking for the # of heterozygotes, f(aa) = 0. 001, we know that the population is at hardy weinberg equilibrium.
