A hypothethical population of 10,000 humans has 6,840 individuals with the blood type AA, 2,860 individuals with blood type AB and 300 individuals with the blood type BB. What is the frequency of each genotype in this population? AA = AB = BB = What is the frequency of the A allele? What is the frequency of the B allele? If the next generation contained 25,000 individuals, how many individuals would have blood type BB, assuming the population is in Hardy-Weinberg equlibrium?
In a population in Hardy-Weinberg equilibrium, if the starting frequency of the A1 allele is 0.5, after 500 generations it will be: Group of answer choices A- 0 b- 1 c- 0.5
Suppose that gene B occurs in a unicorn population where the frequency of the B1 allele is 0.5 and the frequency of the B2 allele is 0.4. What is the frequency of the B3 allele, assuming that there are only 3 alleles in the population? O The frequency of B3 = 0.1 because 0.5 +0.4+ B3 = 1. O The frequency of B3= (0.4)2 = 0.16 O The frequency of B3= 0.9 because 0.5 +0.4 = 0.9 O There is not enough information to determine the frequency of the B3
