NAME____________________ EVOLUTION VOCAB QUIZ Chapter 16 Matching; Within each of the section, match the letter of the term with its definition by placing the letter of the term in the blank. All terms are used and used only once. ______ process by which two species evolve in response to changes in each other A) genetic equilibrium ______ pattern of evolution in which long stable periods are interrupted by brief periods of more rapid change B) punctuated equilibrium C) genetic drift ______ process by which unrelated organisms independently evolve similarities when adapting to similar environments _____ Changes in allele frequency in a small population that are due to random chance and don’t follow the laws of probability D) adaptive radiation E) convergent evolution F) coevolution ______ process by which a single species or small group of species evolves into several different forms that live in different ways; G) mutation rapid growth in the diversity of a group of organisms. ______ A change in the DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals _____ A situation in which the allele frequencies in a population do not change and the population does not evolve * * * * * * * * * * * * * * _____ A trait controlled by a single gene with two alleles A) single-gene trait _____ A trait (like skin color or intelligence) that is controlled by two or more genes B) founder effect C) relative frequency _____ All the genes, including all the different alleles, in a population D) polygenic trait _____ The idea that allele frequency will remain constant unless one or more factors cause those frequencies to change _____ The number of times a certain allele occurs in a gene pool compared to the number of times other alleles for that same gene occur _____ A change in allele frequencies due to the migration of a small subgroup of a population to a new place E) Hardy-Weinberg principle F) gene pool _____ The effect of natural selection when individuals at one end of the normal distribution curve have higher fitness than individuals in the middle or at the other end of the curve A) DISRUPTIVE SELECTION _____ The effect of natural selection when individuals at the extreme ends of the normal distribution curve have higher fitness than those near the center of the curve B) STABILIZING SELECTION _____ The effect of natural selection when individuals near the center of the normal curve of distribution have higher fitness than those at the extreme ends of the population C) DIRECTIONAL SELECTION NAME____________________ EVOLUTION VOCAB QUIZ Chapters 16 & 17 Matching; Within each of the section, match the letter of the term with its definition by placing the letter of the term in the blank.
