19. This has no effect on the gene pool
20. This mutation does not affect the human gene pool because it will not be passed on to offspring
22. A chance event such as a hurricane occurred that caused a population to lose many individual. As a result the population lost alleles because of genetic drift
23. Human population has higher than normal percentage of individuals with a rare genetic disease. The most likely explaination is
24. He read Malthus essays on population did not occur to Darwin on the voyage of the beagle
25. genetic variation necessary for natural selection can be caused by the recombination during meiosis
26. one necessary element of biological species concept is reproductive isolation.
27. individuals organisms in a population All of the above are true
28. Bottleneck
29. Founder effect
