What are the relative fitnesses of the three genotypes

An ethology graduate discovers a very unusual colony of sea gulls. Chicks that are homozygous for the dominant trait Bravado like to tease foxes and 30% of them get eaten. Chicks homozygous for the recessive trait cowardice tend to jump out of the nest when startled and 70% of them fall to their death. Heterozygotes are neither stupid enough to bait foxes nor frightened enough to jump out of the nest. What are the relative fitnesses of the three genotypes?

A) What are the relative fitnesses of the three genotypes?

B) Assume that the initial frequency of Bravado gene was .3 what is the frequency after 1 generation of selection?

C) What are the equilibrium frequencies of the bravado and cowardice genes?
