Question
Migration A group of 460 (with 0.8 allele frequency (p) for the A1 allele) have migrated into this population (of individuals from the previous page). Assuming random mating this group of migrants and the resident population, what will be the frequency (p) of the A1 allele? What will among frequency (q) the A2 allele? Show your calculations all be the and results. Keep 4 significant digits after the decimal. Using a Punned square determine genotype frequencies after migration. Keep 4 significant digits after the decimal.Explanation / Answer
2a) N - Number of individuals in the population = 8460
Nm = Number of migrants into the population = 460
p = allele frequency in the population before migration (residents) = not given here
p' = allele frequency in the population after migration = ?
pm = allele frequency in the migrants = 0.8
m = migration rate = Nm/N = 460/8460 = 0.0543
p' = (1-m) p + m x pm
p is not mentioned in the question (previous page not included)
substitute all the values to get p'
Then q' = 1 - p'
2b)
p'2 = genotype frequency of A1
q'2 = genotype frequency of A2
2p'q' = genotype frequency of A1A2
p' q' p' p'p' p'q' q' p'q' q'q'
