  1. Evolution 1Practice Test

  2. 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

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

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

  5. Question #4 _____ is an example of an allele, _____ is a genotype, and _____ is a phenotype. • B, Bb, hair color • B, Bb, brown hair • Bb, B, hair color • Bb, b, dominant • Dominant, BB, hair color

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

  7. 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

  8. 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

  9. 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.

  10. 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

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

  12. Question #11 • Does evolution act on the genotype or phenotype?
