ANIMAL SCIENCE 221 2 nd Prelim MARCH, 1998 View the Answers Part 1 (Each answer is worth 1 point). 1. The Hardy-Weinberg Law states that a large, random mating population will remain in equilibrium in the absence of three forces that change gene frequencies. These forces are: 1. 2. 3. 2. For a single locus, the genetic value can be partitioned into two components. These are: 1. 2. 3. The magnitude of the impact of migration on gene frequencies depends on two things. These are: 1. 2. 4. For an autosomal locus, if gene frequencies in males and females are different, it takes two generations of random mating to reach equilibrium. What happens in each generation? Generation 1 2
