Blood Type Evolution Prediction

APBIO-R7GYZ4

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.

A

0%

B

3%

C

16%

D

40%
