You are studying ABO blood groups, and know that 6.25% of the population has genotype I^AI^A and 42.25% of the population has Type O blood. What is the expected frequency of blood type B? A) 14% B) 6.5% C) 51.5% D) 13% E) 1%

The expected frequency of blood type B is 14%. This is because the alleles for blood type B are I^B and i. The frequency of the I^B allele can be calculated by subtracting the frequency of the I^A allele (6.25%) and the frequency of the i allele (42.25%) from 100%. This gives us a frequency of 51.5% for the I^B allele. The frequency of the i allele is 42.25%. The expected frequency of blood type B is the product of the frequencies of the I^B and i alleles, which is 14%.
