The term "n" refers to the size of a population, that is, the number of individuals in that population. In general, in a sample of n individuals, the frequency of an allele is: - Answer-the number of occurrences of the allele divided by twice the number of individuals in the sample (2n) If a population is not in Hardy-Weinberg equilibrium, we can conclude that: - Answer-evolution has occurred because one of the assumptions of the Hardy-Weinberg equilibrium has been violated The goldenrod ...

3. ________ isolating mechanisms prevent the fusion of gametes where as _______ isolating mechanisms prevent the proper functioning of the zygote. - Prezygotic, post zygotic • Adaptive radiation - o Existence of groups of closely related species that have recently evolved from a common ancestor by adapting to different parts of the environment. This is common in situations in which species occur in an environment with few other species and many available resources. o Adaptive radiation re...

What is reinforcement? How does it play out? What is it's role in the speciation process? correct answers secondary contact is for selection to "reinforce" existing isolating mechanisms -selection favors the evolution of prezygotic isolating mechanisms -hybrids unfit-> selection favors assortative mating-> mate preferences lead to decline in hybridization -Coyne and Orr: prezygotic isolation evolves faster in sympatric species -mate choice based on toad calls How is reproduct...
