Question
Among a population of 220 bears on a small island the frequency of the MC1R298Cys was 0.1 and the population was at Hardy Weinberg equilibrium. Then 30 black bears migrated to the small island from the mainland where the MC1R298Tyr was fixed. What are the new allele frequencies of the admixed population? Choose all the frequencies needed to complete the sentence. Among the admixed island population the f(MC1R298Tyr )= p= ______ and f(MC1R298Cys) = q= ________ , the new allele frequencies indicate that the island population has evolved as a consequence of the migration.

Explanation / Answer
Given that:
Total Population = 220
Among them MC1R298Cys = 01 frequency = 10%
No of individuals with this allele are (220 x 10/100) = 22
And the population is in Hardy weinberg equilibrium ,the allelic frequency of MC1R298Tyr will be 0.9 = 90%
No of individuals in with this allele are 220 x 90/100) = 198.
Admixed population total = 220+30 = 250
Total no of individual with MC1R298Tyr = 198 +30 =228
Allelic frequecny MC1R298Tyr (p) = 228/250 = 0.912
Allelic frequency MC1R298Cys (q) = 22/250 = 0.088
Hence the values of p =0912 (ie., option D)
q = 0.088 (ie., option F)
