Compare and contrast adaptive and nonadaptive

This preview shows page 2 - 4 out of 5 pages.

Compare and contrast adaptive and nonadaptive mechanisms of evolution. (2) 8. In the following scenario, state what evolutionary mechanism is likely to occur and why: (2 points each = 10 points) a. A few polar bears are separated from their population by a random ice drift. Consider this new smaller population. b. A disease ravishes a population of wild corn. a. Two populations of hermit crab live in the same lagoon. b. A volcanic eruption kills most of a certain species of beetle. c. A population of viruses has an error-prone RNA polymerase.
13. List and describe the five conditions required for a theoretical population to be in Hardy-Weinberg equilibrium.(10) 1) 2) 3) 4) 5) 9. Can a natural population ever be in Hardy-Weinberg equilibrium? (1) 15. Eye color in Jabberwocks is controlled by a single gene with two alleles that exhibit simple dominance. Flame eyes (F) are dominant to brown eyes (f), with individuals of Ff genotype having flame eyes. In a population of 500 Jabberwocks, 300 have brown eyes; the rest have flame eyes. The population is in Hardy-Weinberg equilibrium. Let p represent the frequency of the dominant allele and q represent the frequency of the recessive allele. (1 point each = 6) The Hardy-Weinberg equation is: p 2 + 2pq + q 2 = 1 p + q = 1 a. How many total alleles for the trait are in the population?
