A group of 460 individuals (with 0.8 allele frequency (p) for the A1 allele) have migrated into this population
(of 8,000 individuals from the previous pages). Assuming random mating among this group of migrants and
the resident population, what will be the frequency (p) of the A1 allele after a generation of random
mating? What will be the frequency (q) of the A2 allele after a generation of random mating?
Now consider a group of 3,000 migrants with 0.8 as the allele frequency (p) for the A1 allele. Assuming
random mating among this group of migrants and the resident population, what will be the frequency (p) of
the A1 allele? What will be the frequency (q) of the A2 allele?
Now consider a group of 3,000 migrants with 0.1 as the allele frequency (p) for the A1 allele. Assuming
random mating among this group of migrants and the resident population, what will be the frequency (p) of
the A1 allele? What will be the frequency (q) of the A2 allele?
What pattern do you see in the changes in allele and genotype frequencies of the initial population, given
the different migrant groups? Briefly explain the key characteristics of the different migrant groups
leading to these changes.
