On the basis of other ancestor to humans and mice lived 100 million years ago. clock is operating, rats and mice split from each other A) 5 B) 10 C) 25 D) 50 E) 100 e and humans differ by 20 substitutions in their globin genes, and rats evidence, we know that the molecular Assuming the million years ago.

Based on the phylogeny of primates shown above, which of the following traits is shared by ALL primates? A) prehensile tail (i.e. a tail that can grasp objects) B) opposable thumbs C) bipedalism D) eyes in the front of the head E) Both B &D; 36. When the conditions of the Hardy-Weinberg equilibrium are met A) evolution occurs B) evolution does not occur. C) gene frequencies in the population change over time. D) none of the above. 37. Geographic isolation can accelerate speciation because A) it increases the level of natural selection B) it restricts gene flow C) it counteracts natural selection D) it increases the level of mutation E) it leads to polyploidy

Explanation / Answer

34. According to the 20 substitution, in their globin gene they are separated by 10 million year ago. Hence, option b is correct.

35. Based on the phylogeny, all the primates have eyes in the front of the head. Hence, option d is correct.

36. Hardy –Weinberg law state when evolution is not happening, then frequency in a population does not change over the time. Hence, option b is correct.

37. Because , it increases the level of natural selection. Hence, option a is correct.

39. Because mutation that occur in germ cells are inherited from one generation to another. Hence, option d is correct.

40. Postzygotic isolation inhibits the formation of fertile offspring. Hence, option e is correct.

41. Inbreeding can cause reduce genetic diversity. Hence, option a is correct.
