Question

Question;Gene flow has a greater effect on large populations than small populations.AnswerTrueFalseDuring the genetic drift simulations, which population size should have exhibited the greatest amount of variation in allele frequency?Answer1001000Under Hardy-Weinberg equilibrium, are recessive phenotypes eventuallyeliminated?AnswerYesNoUnder Hardy-Weinberg equilibrium, which frequency of A yields the highestfrequency of AA?0.80.60.50.40.2In regards to the guppy study in natural ponds, for which ponds did male guppies have the highest mean number of spots?Answerponds with no predatorsponds with cichlids onlyponds with killifish onlyponds with cichlids and killifishIn regards to the guppy study in natural ponds, for which ponds did male guppies have the lowest mean number of spots?Answerponds with no predatorsponds with cichlids onlyponds with killifish onlyponds with cichlids and killifishAnswerCan you explain any differences in average spot number associated with thedifferent type of predators?AnswerThere should be no difference in selective pressure from killifish versus cichlids.Cichlids are apparently more dangerous as predators to guppies, and thus can be expected to exert a stronger selective pressure affecting spot number.Killifish are the more dangerous predator to guppies and thus they would be more likely to exert the stronger selective pressure.What was the average number of spots at the start of all your experiments?2.03.04.05.0
