1) Avena fatua is a species of wild oat (a type of grass). Jain and Marshall studied wild oat population genetics in California. One of the traits they examined was the pubescence (hairiness) of the leaf sheath, which is controlled by a single locus with two alleles, written L and l. They found that the frequencies of genotypes in one population were [LL 57.1% Ll 7.1% ll 35.8%]. Calculate value of the inbreeding coefficient, F.
2) Suppose you put 500 northern Fundulus fish (all genotype AA) and 500 southern fish (all genotype BB) in a large tank, allowed them to breed freely, and then raise the offspring into the next generation. The relative fitnesses of possible genotypes in this system are wAA = 0.25, wAB = 1, and wBB = 0.67. What will be the genotype frequencies after one generation of random mating? What will be the genotype frequencies after the second generation of random mating?
