Biology Unit 7 Lesson 3 Distribution of Traits Quick Check Answers

Question

1. Which of the following factors may contribute to a population maintaining Hardy-Weinberg equilibrium?
Answer - There are no mutations in the DNA of the population.

2. You are studying a population of penguins in Antarctica. Your DNA analysis of this population reveals that for the feather color pattern gene, 35 individuals are homozygous dominant, 35 individuals are heterozygous, and 30 individuals are homozygous recessive....etc...etc...
Answer - The recessive phenotype in this population may serve as an adaptation in this environment.

3. A scientist is studying the population of Cape Fox over four generations to determine if the population is in Hardy-Weinberg Equilibrium. Use the data below to determine if this population is in Hardy-Weinberg Equilibrium.
Answer - No, the population is not in Hardy-Weinberg Equilibrium because the frequencies of alleles have changed over the four generations.

4. Gene flow from one species to the genome of another by interbreeding between species is called
Answer - introgression.

5. In which of the following populations would you expect to find a change in allele frequencies from one generation to the next?
Answer - A population of turtles that routinely breeds with another closely related species of turtle.
