Question

The ABO blood typing system in humans is determined by a single locus with three alleles A,B, and O. Worldwide, the frequency of the B allele is 16%.
If blood type is not a factor for either natural or sexual selection and mutations to the locus are negligible, predict the frequency of the B allele in three generations.

Solution

The correct option is C 16%
The ABO blood typing system in humans is determined by a single locus with three alleles, A, B, and O. It is given that, the frequency of the B allele worldwide is 16%. If it is not undergoing natural or sexual selection and also if no mutation is taking place in this allele, the frequency of the B allele will remain same over many generations. Hence, the frequency of the B allele in three generations will be 16%.
Thus, the correct answer is '16%.'
