Introduction:
The Hardy-Weinberg principle describes the establishment of genotype frequencies in sexually-reproducing organisms. Genetic equilibrium will be achieved if the given conditions are followed:
1) No mutations occur in a population.
2) Population is closed to migration from other population.
3) Individuals in a population mate randomly with their genotypes.
4) All genotypes in a population survive and are able to reproduce.

Using the observed counts for each genotype, how do you find the expected values with those numbers and the frequencies?
What is one assumption of the Hardy-Weinberg law that does not hold true for all populations?
Suppose there is an autosomal locus of 2 alleles, A1 and A2, with probabilities (frequencies) p1 and p2, and the genotype probabilities (frequencies) are P(A1A1) = p1*p1, P(A1A2) = 2*p1*p2, and P(A2A2) = p2*p2, respectively. Prove the Hardy-Weinberg Law, i.e., after one generation of random mating, the genotype probabilities (frequencies) in the offspring are also P(A1A1) = p1*p1, P(A1A2) = 2*p1*p2, and P(A2A2) = p2*p2. Hint: List all possible combinations of random mating. Then list the probabilities of the resulting genotype probabilities (frequencies) in the offspring. Combine the probabilities of random mating and resulting genotype probabilities (frequencies) in the offspring.
