- Q1Which of the following statements describes what all members of a population share?They are members of the same species.They are temporally isolated from one another.They are geographically isolated from one anotherThey are members of the same species.30s
- Q2The combined genetic information of all members of a particular population is the population’srelative frequencygenotypegene cauldrongene pool30s
- Q3Which statement about gene pools is typically true? [Hint: you might want to approach ths question by eliminating answers you know to be false]They contain two or more alleles for each gene.They contain only dominant allelesThe relative frequencies of the alleles never change.They belong to two or more interbreeding species.30s
- Q4If an allele makes up one fourth of a population’s alleles for a given trait, its relative frequency is100425 percent7530s
- Q5A single-gene trait that has two alleles and that shows a simple dominant-recessive pattern will result infour phenotypesmillions of phenotypesone phenotypetwo phenotypes30s
- Q6The effects of genetic drift on evolutionary change or most pronounced in populations thatare formed from new speciesare smallare very largehave unchanging frequencies30s
- Q7The type of genetic drift that follows the colonization of a new habitat by a small group of individuals is calledthe founder effectstabilizing selectionhardy-weinberg principledirectional selection30s
- Q8The genetic equilibrium of a population can be disturbed by each of the following EXCEPTa large population sizenon-random matingorganisms moving into and out of the populationmutations30s
- Q9The allele frequencies of a population are more likely to remain unchanged ifthe mutation rate increasesthe population size is reducedall mating is randomthere is frequent movement of organisms into and out of the population.30s
- Q10What situation might develop in a population having some plants whose flowers open at midday and other plants whose flowers open late in the day?genetic driftbehavioral isolationtemporal isolationgeographic isolation30s
- Q11The situation in which allele frequencies of a population remain constant is callednatural selectionevolutiongenetic equilibriumgenetic stability30s
