One of the original Amish colonies rose from a ship of colonists that came from Europe. The ship s captain, who had polydactyly, a rare dominant trait, was one of the original colonists. Today, we see a much higher frequency of polydactyly in the Amish population. This is an example of: natural selection genetic drift founder effect b and c
The phenomenon in which chance events cause unpredictable changes in allele frequencies is called: a. gene flow. b. genetic drift. c. inbreeding. d. balanced polymorphism. e. stabilizing selection.
An Eastern European immigrant carrying the allele for Tay-Sachs disease settled in a small village on the St. Lawrence River. Many generations later, the frequency of the allele in that village is statistically higher than it is in the immigrants homeland. The high frequency of the allele in the village probably provides an example of: a. natural selection. b. the concept of relative fitness. c. the HardyWeinberg genetic equilibrium. d. phenotypic variation. e. the founder effect.

B) Artificial Selection• Explain how artificial selection is like natural selection.• Why are quail useful subjects for an experiment on selection? What other organisms share similar characteristics?
2) A species is a group of individual organisms that interbreed and produce fertile, viable offspring. According to this definition, one species is distinguished from another when, in nature, it is not possible for matings between individuals from each species to produce fertile offspring. Evolution is an important mechanism in the formation of new species. The evolution of a new species requires several components including all, BUT A) Evolution of a new species requires a long time. B) Evolution of a new species requires the need for a genetic change. C) Evolution of a new species requires a separation that prevents interbreeding. D) Evolution of a new species requires mutations that produce new genetic traits. Not Graded
