Chapter 10, Problem 14P

Summary Introduction

To analyze:

Frequency of ${\text{β}}^{\text{s}}$ allele in central West African population is $15\%.$ Frequency of ${\text{β}}^{\text{s}}$ allele in population from the southern tip of Africa is less than $1\%.$

The question asked to conclude the approximate reason for the different frequencies of the allele in the given African populations.

Introduction:

An individual has two alleles for one gene. On the other hand, when multiple alleles for one gene are present in the population, these alleles represents that the population is poly-morphic. The contribution and number of a particular allele in a population are counted as the $\%$ frequency. The frequency of a large population is the same generation after generation, but some rules should be followed to maintain frequency, i.e., random matting, large population size, no selection criteria. These rules are proposed by the scantiest Charles Robert Darwin.
