Sandra and John have a flock of 4500 sheep, and they started to concern about the wool color after the flock has been closed for random breeding/mating for an extended period. One day, they have counted and found that 950 sheep were white, and the remainders were black. Assume that black wool is controlled by a single locus and the allele for black color is completely dominant to white. Let B represent the black allele and b represent the while allele. Assume HW equilibrium, A) What is the observed genotypic frequency for the bb genotype?
B) What are the expected gene frequencies for B and b alleles?
C) What are the expected genotypic frequencies and counts for each of the three genotypes?
