Suppose a forest fire creates a habitat change such that where a lizard that has brown skin was formerly in hardy-weinberg equilibrium, natural selection by predators is creating a selective disadvantage for a dark brown allele. this allele (b) has been at a frequency of 0.9 and the light brown allele (b) has been at a frequency of 0.1. the allele is additive in its effect on the trait, and the new fitness levels of the genotypes after the fire are: bb = 0.4 bb = 0.7 bb = 1.0 based on these fitness values and initial genotype frequencies, we calculate a mean fitness of the population for the next generation of 0.46. given this information, what is the frequency of the dark brown homozygote (bb) after 1 generation? enter your answer as a percentage, not a decimal, but do not enter the % sign.
