36. In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.1. What is the percentage of the population that is heterozygous for this allele?

37. You sample a population of butterflies and find that 42% are heterozygous at a particular locus. What should be the frequency of the recessive allele in this population?

8. How did some ancestral sea-run stickleback populations come to live exclusively in freshwater?  

Suppose you wanted to bundle the 3 issues together and present the recruiter a choice between two different offers that include all three issues that are of EQUAL value to you. Construct two such offers below. For full credit you need to provide the description of the option within each issue, the points your chosen options are worth and the total point values of your two bundles.

4. Like Bear Paw Lake, nearby Kalmbach Lake is an Alaskan lake that historically had no native predatory fish. The Alaska Department of Fish and Game started introducing rainbow trout into Kalmbach Lake in 1982. Prior to these introductions, the pelvic reduction was common in this stickleback population. The rainbow trout are known to prey on stickleback. What would you hypothesize has happened to the stickleback population in the more than 30 generations that have elapsed since the trout was introduced?  

19. Which of the following is a reason for collecting specimens by random sampling when conducting the type of research in this virtual lab?

1. Based on what you have learned so far about threespine stickleback fish, which of the following statements is most accurate:  

39. In a hypothetical population of 1,000 people, tests of blood-type genes show that 160 have the genotype AA, 480 have the genotype AB, and 360 have the genotype BB.   What is the frequency of the B allele?

What media outlet did the reporter who broke the Kaepernick story work for?

Radio frequency identification (RFID) technology can be very useful in tracking and tracing products that have long shelf lives, including for products such as food and flowers that have limited shelf lives.
