152 Evolution Exam- Funeral Directing Questions And Answers

The two major sources of genetic variation in a population are: A. Mutation and genetic drift B. Mutation and recombination C. Immigration and emigration D. Natural selection and selective mating E. Adaptive radiation and divergent selection {Ans: B. Mutation and recombination}Which of the following mechanisms would NOT interfere with the action of natural selection acting on a population? (a) A population that is very small in size (b) High rates of recombination (c) Selection on a gene that codes for many different traits (d) Low genetic diversity underlying a trait under selection {Ans: (b) High rates of recombination}A population is in Hardy-Weinberg equilibrium and the frequency of a is 0.4. Given this, which of the following would be the most common genotype in the population? A. A B. a C. AA D. Aa E. aa {Ans: D. Aa}10 to 12. Evolution in a rapidly reproducing population (compared to a population that reproduces less frequently) can be faster because: T/F 10. the mutation rates per gene locus are faster in small populations compared to large populations. T/F 11. random events can have larger effects on allele frequencies T/F 12. more reproduction events per unit time translates into more
