Earwax

APBIO-VWG9QZ

Human earwax texture is determined by a single gene with two alleles: wet and dry. Dry is recessive, and wet is dominant.

Evidence suggests that the dry allele first appeared in Eastern Asia about 2,000 generations ago. The frequency of the dry allele in a European population is 0.15.

What percentage of this population is expected to have the wet earwax phenotype?

A

0.02

B

0.26

C

0.72

D

0.98
