Genetic frequency – In ladybugs, wings with 4 spots

| August 31, 2017

Genetic frequency

1. In ladybugs, wings with 4 spots are recessive to those with 2. Assume 11% of the ladybugs have 4 spot wings. If the mutation rate of 2 spot to 4 spot alleles is 0.047, what percentage of the next generation will be heterozygous?

2. You look at two populations of moose, one from Canada, and one from Newfoundland, an island east of the North American continent. Canadian moose have a dominant allele for antler size with a frequency of 0.34. Newfie moose have a frequency of 0.72 for the same allele. Assuming that 1 percent of the moose migrates from Canada to Newfoundland (an amazing dispersal rate for a terrestrial macrovertebrate across an oceanic body of water), what would be the allele frequency after 2 generations?
