Ohio Biology EOC Review Evolution/Diversity EXAM QUESTIONS AND ANSWERS 100% SOLVED (Newest 2025) What is genetic drift? - Correct Answers ✅A change in allele frequencies caused by random events Why is genetic drift common in smaller populations? - Correct Answers ✅An individual with a particular allele may leave more descendants by change, and the allele frequencies will change more drastically.If the allele frequency is not constant, what is occurring? - Correct Answers ✅EVOLUTION If a species is evolving, is genetic equilibrium established? - Correct Answers ✅NO What factors can disturb genetic equilibrium and cause evolution to occur? (5) - Correct Answers ✅Non random mating, small population size, immigration or emigration, mutation, natural selection.What is sexual selection? - Correct Answers ✅natural selection arising through preference by one sex for certain characteristics in individuals of the other sex. 1 / 2
Ohio Biology EOC Review Evolution/Diversity EXAM QUESTIONS AND ANSWERS 100% SOLVED (Newest 2025) How does sexual selection lead to evolution? - Correct Answers ✅The allele frequencies change due to a preference for or against an allele, so genetic equilibrium is thrown off.In what types of populations do genetic drift occur? - Correct Answers ✅Small populations, because a certain allele can become more common and represented.Immigration - Correct Answers ✅Moving into a population Emigration - Correct Answers ✅Migration from a location How does immigration and emigration cause genetic drift? - Correct Answers ✅Immigration introduces new alleles to a gene pool, and emigration can remove alleles from a population.How do mutations cause genetic variation? - Correct Answers ✅Mutations cause new alleles to appear in a gene pool, due to a changed protein, and this leads to a change in allele frequencies and evolution.
