Document Summary
Punnett square when alelle proportions in the parental generation are uneven: A and a in f0 generation: q = fr(aa) + 0. 5fr(aa, p = fr(aa) + 0. 5fr(aa, or, if you are given a proportion, subtract it from 1 to get the other proportion. 1. cross all the possible combinations of allele(s) that each parent could transmit to an offspring (if it was 2 traits, ab ab ab and ab would line the top row) 1. use the multiplication rule to calculate the probability of obtaining each genotype in the offspring generation. Hardy weinberg extends mendelian theory (for individuals) to a population scale. Reveals relationship between allele frequencies and genotype frequencies when evolution doesn"t occur. Allele frequencies should remain constant at hardy-weinberg equilibrium. If the population is not at hwe, then one of these conditions is broken. Random mating (otherwise, genotype frequencies change (not allele frequencies): no different in survival or reproductive success given a particular allele.
