Chapter 15 Hardy Weinberg and Genetic Drift/Population Size

Question 1

The panels indicate the effects of genetic drift on the heterozygosity of a single gene (starting at 50% each allele) through 50 generations of random mating. Indicate the largest population to the smallest based on maintained heterozygosity.
