Evolution 2 Practice Test

Question #1 There was a population of winged and non- winged creatures. One day, a volcano erupted and the non-winged died because they could not fly away. This is Gene flow Genetic drift Natural selection Geographic isolation

Question #2 Which of these is the result of convergent plates? Mountain ranges Ocean spreading Volcanic eruptions Trenches and valleys

Question #3 In order for evolution to take place, there must be variation between Populations Species Kingdoms Individuals

Question #5 If the gametes of two organisms are not combining, which of the following is most likely occurring? Extinction Mutation Hybridization Reproductive isolation

Question #6 A gene pool consists of all the Genetic variations of a species Genetic variations in a population Adaptations within a species Different organisms in a population Adaptations within an environment

Question #7 Which of the following is NOT part of Darwin’s theory of natural selection? Only some organisms survive to reproduce. Favorable variations accumulate over time. Survival favors some organisms over others. Use and disuse of body parts determines their fate

Question #8 Which of the following is an effect of gene flow? Write ALL that apply. Decreased genetic variation. Increased genetic variation. Increased extinction. No speciation.

Question #9 What is the most likely cause that a green haired individual is born in a brown haired population? Natural selection Genetic drift Mutation Reproductive isolation

Question #10 Is variation within a species good or bad? Why?
