The coat color gene of a population of squirrels is defined by a dominant allele G, which encodes a gray coat, and a recessive allele g, which encodes a black coat. In a population, genetic typing reveals the genotypic distribution to be 50 GG, 30 Gg, and 20 gg. If this population is in equilibrium, then what should the genotypic frequency of Gg squirrels in this population be?

Answer #1

The allele frequency gg q = 0.35

So P+Q = 1 ; P = 1-0.35 = 0.65

The genotypic frequency of Gg = 2PQ = 2 X 0.65 X 0.35 = 0.46

    In mouse coat color, the allele G (for gray color) is dominant to black, which occurs only with the double recessive gg. A recessive mutation homozygous at another site, kk, gives albino mice regardless of the G/g genotype. Allele K allows expression at the G/g locus. The F1 cross are all GgKk and are gray in color. Do the F2 cross and indicate the phenotype ratios.

    A zoologist is investigating a population of squirrels whose coat color is controlled by a single gene whose two alleles (B1 & B2) are co-dominant. B1B1 individuals are black, B1B2 individuals are brown, and B2B2 are tan. She surveys the population and finds 600 black squirrels, 256 brown squirrels, and 112 tan squirrels. Is this population in HWE? If not, what might explain this pattern? Make sure to show your work.

    - In the 1960s, a population of squirrels (Sciurus carolensis) was being studied in Alabama and the coat color of the squirrels was found to range from the more common gray color (dominant) to the less common red color (recessive). When scientists sampled an area, they found 536 gray squirrels and 64 red squirrels. Assuming the population is at Hardy Weinberg’s equilibrium, In the year 2015, another group of scientists studied the squirrel coat color and found that the population...

    Part 1: Assume a population is in Hardy-Weinberg equilibrium and you have observed 600 animals for coat color. The results are: Black 504 Red 96 The gene for black coat color is dominant. Calculate gene and genotypic frequencies. part 2: Assume a population in equilibrium, where 4% of the animals have red coat color. (The allele for red coat color is recessive). Calculate gene and genotypic frequencies in this population.
