EVOLUTION 1 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 & valleys

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

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

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 a result 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 Genetic mutation Reproductive isolation

Question #10 Increased variation benefits a species because ___. odds of speciation increases fewer species are made odds of mutations increases odds of species’ survival & reproduction increases

Question #11 Evolution acts on phenotype because __. a. phenotype determines genotype b. phenotype overpowers than genotype c. phenotype determines survival & reproduction chances d. only the phenotype is passed on
