Mutations in a particular developmental gene occur at a rate of 10-4 in a population of Kegonsa dragonflies. The mutant alleles are fully recessive and lead to a crumpled wing phenotype that is only 10% as fit as wild type. What will be the equilibrium frequency of mutant alleles? If applicable, report exactly 3 significant digits.

Monona salamanders have a range of shades from light green to dark green. Researchers have determined that the shading is controlled by exactly 4 genes whose segregating alleles act additively. Salamanders that are heterozygous for each gene are crossed. What is the frequency of individuals that have the darkest phenotypic class in the next generation? If applicable, report exactly 2 significant digits.
