Hardy Weinberg assignment P + Q = 1 In which P represents frequency of dominant allele and Q represents frequency of the recessive allele P2 + 2PQ + Q2 =1 P2 represents frequency of homozygous dominant 2PQ represents frequency of heterozygous Q2 represents frequency of homozygous recessive Consider a population of beetles on an island. There are 1000 beetles and they have different colored wings. Black wings are dominant over silver wings. Calculate the allele and the genotypic frequencies in...

2. The lubber grasshopper is a very large grasshopper, and is black with red and yellow stripes. Assume that red stripes are expressed from the homozygous RR genotype, yellow stripes from the homozygous rr genotype, and both from the heterozygous genotype. A. If two heterozygous grasshoppers were crossed, what would be the genotypic ratio of the F1 generation (RR:Rr:rr)? Fill in the Punnett square. B. What genotypes would be produced by crossing a grasshopper with both color stripes and one...
