Question

117. In very small populations, genetic variation is often lost through genetic drift. If the population size of a mammal on an isolated island is 50, what percentage of its genetic variation is lost every generation? a. 0.01 b. 0.5 C. 0.1 d. 0.05
​

Answer 1

Answer:

Musoma,tanazania

Explanation:

A population of infants from Musoma, Tanzania, was scored for the β-hemoglobin

locus genotype (determined by a single autosomal locus with two alleles, Aand S) as

follows:

Genotype AA AS SS Total

Number 189 89 9 287

Characterize this population by its genotypic frequencies. Characterize the gene pool by

the allele frequencies for A and S. Using the Hardy–Weinberg law, predict the genotypic

frequencie

Answer 2

Answer:

a. 0.01

Explanation:

1% of genetic variation is lost every generation.
