Evolution Answers

The acoustic lesser wax moth, Achroia grisella, are obligate symbiotes of honeybees (live in association with them).  Males attract females by emitting ultrasonic pulses from their wings. The sound the moth emits can also attract their predators, bats. Wing pulse rate has been demonstrated to be controlled by one gene with two alleles, F (dominant, fast) and f (recessive, slow).  

This population is not currently in Hardy-Weinberg equilibrium, but scientists have determined that environment and other selection factors such as bat predation are stable over recent time. In paragraph form, discuss two other mechanisms of evolution that could be acting on this population, and what information and/or data you would need to support each evolutionary agent. You will be marked according to the written answer rubric on your answer, use of scientific reasoning, and avoiding misconceptions. (5 points) You should have a maximum of 6 sentences.

A dwindling population of 1000 frogs occupies an isolated area in Costa Rica. To help preserve the species, scientists caught 20 frogs to start a new population in a nearby area. This species has a gene that affects eye shape. The 1000-member wild population has two alleles for this gene: R and r, with frequencies 0.7 and 0.3, respectively. What will be the allele frequencies of R and r in the 20-member founder population?
