Questions:
1. Dr. Martin Brenner and his team have built a space ship which can travel at the speed of light (186,000 miles per second) and travel to parallel dimensions. Dr. Brenner is interested in the population genetics of a unique species in the Upside Down dimension. Using his space ship, he travels to the past 11 million years to execute his research and study a population of Demogorgon draconems, the other world's only species. It weighs 7,000 kg (15,432 lb) and has six stages of development from larva to adult. The species has two skin colors, blue (dominant) and grey (recessive). Dr. Brenner observed 294 blue Demogorgon draconems and 56 grey Demogorgon draconems during his study. Assume the population is in Hardy-Weinberg equilibrium.
A. Calculate the frequency of the blue allele in the population?
B. How many of the animals were heterozygous?
C. Calculate the frequency of the homozygous recessive genotype?
On a second trip to the Upside Down, he observed 150 Demogorgons. Assume the population is still in Hardy-Weinberg equilibrium.
A. How many do you think will be grey?
B. How many do you think will be blue?
C. How many of the blue animals are homozygous for the dominant allele?
2. In a population of Demogorgon draconems that are mating randomly, 25 percent of the Demogorgons have purple scales (purple is an autosomal recessive (p) trait) and 75 percent have yellow scales (the normal color P). Assume the population is in Hardy-Weinberg equilibrium.
A. Calculate the allelic frequencies of P.
B. Calculate the allelic frequencies of p.
C. Calculate the genotypic frequencies of P?/?P.
D. Calculate the genotypic frequencies. P?/?p?
