Question

On the same island the frequency of the M blood type allele is 0.62. What then would be the number of inhabitants expected to have the MN blood type? The inhabitants of this island are pacifists. After several years, tribes on two neighboring islands every year capture several inhabitants of the peaceful island and take them home for lunch. One tribe likes MM blood type and the other likes NN blood type. Over several hundred generations would the frequency of the M blood type allele change? If so, in which direction and why?

Explanation / Answer

21.If the frequency of the allele is 0.62 .This means that 62 % of the people on that island have M blood type allele.Thus the remaining allele would be-

1- 0.62= 0.38 i.e 38% would be MN blood type.

22. Yes the frequency of an allele can change in several years by mutation, natural selection, non randommating, migration or genetic drift. It is difficult to predict the direction of change in allele frequency because we do not know what quantity or measure has brought about the change in frequency of which allele.
