- 1. Multiple ChoiceGenetic drift is change in the allele frequency of a population due to...random chancenatural selectionnon-random mating (sexual selection)artificial selection
- 2. Multiple ChoiceGenetic Drift is more likely to happen in...aquatic populationssmall populationsterrestrial populationsolder populations
- 3. Multiple ChoiceA virus killed most of the seals in the North Sea (e.g. dropped the population from 8000 to 800). In an effort to help preserve the species, scientists caught 20 of the remaining seals and used them to start a new population in the northwest Pacific Ocean. Which of the following statements would accurately describe the new population?The new seal population is genetically less diverse than the original populationThe new seal population is genetically more diverse than the original populationThere is equal genetic variety compared to the original populationNone of the answers
- 4. Multiple ChoiceThis mechanism of evolution occurs when individuals migrate between populations.ExtinctionGene flowGenetic driftNatural Selection
- 5. Multiple Choice
This model shows a how populations of organisms can change. Which of the following concepts is best illustrated by this demonstration?Natural selectionGenetic driftExtinctionGene flow - 6. Multiple ChoiceWhich of the following is an example of the bottle neck effect?Bald Eagles are hunted until near extinction, population recovers.Small group of iguanas floats to an island, starts a new population.Red fox pups are more likely to survive in a snowy environment if they are born white.Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.
- 7. Multiple ChoiceWhich of the following is an example of the founder effect?Bald Eagles are hunted until near extinction, population recovers.Small group of iguanas floats to an island, starts a new population.Red fox pups are more likely to survive in a snowy environment if they are born white.Farmer chooses seeds from largest apples to plant next year. This results in larger apples from year to year.

- 13. Multiple ChoiceA change in the genetic composition of a population as a result of descending from a small number of colonizing individuals is called:founder effectbottleneckgenetic driftgene flow
- 14. Multiple ChoiceFive hundred years after the deer had established a flourishing population in the park, a few of them venture back to their original woods and have babies with the deer there.Genetic DriftMutationsNon-random matingGene flow

- 17. Multiple ChoiceNatural selection states that organisms are best suited for their environment if they ____________ and ____________.Survive and ReproduceSurvive and PredateSurvive and ParasitizeSurvive and Adapt
- 18. Multiple ChoiceAccording to the bead lab, Genetic drift (bottleneck or founder) tends to ___________ genetic variation (diversity)IncreaseDecreaseStabilizeExaggerate
- 19. Multiple ChoiceIn the bead lab, changes in the alleleic frequency (proportion of three color variants) was most drastic in which trial?The trial when 20-15 beads were drawn.The trial when less than five beads were drawn.The trial where students where allowed to choose which beads were selected.The number of beads drawn has no effect on allele frequencies.
- 20. Multiple ChoiceGene Flow tends to ___________ genetic variation (diversity)IncreaseDecreaseStabilizeExaggerate
- 21. Multiple ChoiceWhere the better adapted organisms survive to pass traits along to offspring.EvolutionNatural SelectionExtinctionArtifical Selection
- 22. Multiple ChoiceWhat do we call change over time?EvolutionNatural SelectionNatural VariationSpeciation
- 23. Multiple ChoiceExplain why Ellis-van Creveld syndrome is an example of the Founder effect.Babies born with this syndrome have a greater chance of surviving.Most of the Amish where killed in war and there was a higher proportion of the genes for the syndrome in the survivors.A small population of Amish moved to Pennsylvania who had a larger proportion of genes for the syndrome.The Amish lifestyle exposes them to more mutagens so they have a higher incidence of the syndrome than the rest of the population.
- 24. Multiple Choice(True/False) In the bead lab, genetic drift could result in the loss of a color from the population.TrueFalse
- 25. Multiple Choice(True/False) I am a quizizz ninja.TrueFalse
