Question 1

Biologists are studying a human population in a remote village in Siberia. They find that the frequency of individuals homozygous for N alleles is 0.57 and the frequency of heterozygotes is 0.18. The genotype frequencies do not change in the next generation.

What is the frequency of the M allele?

Answer 1

NN-.57
MM-.18

MN= .57+.18=75
100-75=.25<—- MN

f(M)= f(MM)+.5 f(MN)
=.25+1/2(.18)

f(M)=.34
