Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consisting of 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there is no migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E. Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygotes have shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggy individuals, and 84 rough individuals. Suppose you watch the buffalo and discover that while all the females breed, a small number of males(10) establish breeding harems, while the other males do not breed. a) What is the effective population size of this herd? That is, what size "ideal" population of balanced sex ratio would have genetics similar to this population? b)How does the effective population size compare to the actual population size? c) Under Hardy-Weinberg equilibrium, what is the expected heterozygosity of this population? What is the actual heterozygosity? d) Using the measured heterozygosity as a starting point, after one generation, what is the expected loss of heterozygosity due to drift? Which of the Hardy-Weinberg assumptions need to be re-examined in this herd?
Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consisting
of 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there is
no migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E.
Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygotes
have shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggy
individuals, and 84 rough individuals.
Suppose you watch the buffalo and discover that while all the females breed, a small number of males(10) establish breeding harems, while the other males do not breed.
a) What is the effective
balanced sex ratio would have genetics similar to this population?
b)How does the effective population size compare to the actual population size?
c) Under Hardy-Weinberg equilibrium, what is the expected heterozygosity of this population?
What is the actual heterozygosity?
d) Using the measured heterozygosity as a starting point, after one generation, what is the
expected loss of heterozygosity due to drift? Which of the Hardy-Weinberg assumptions need to be re-examined in this herd?
