When populations of closely related pied flycatchers and collared flycatchers live in different geographic areas, the males of b
oth species look a lot alike. However, when populations of the two species share a common geographic area, there are significant differences in the appearance of the two species. What conclusions might you draw from this situation? (ebook Module 14.10)A. Even though the colors of the males of the two species are very similar in the geographically isolated populations, you would expect that when researchers performed mate-choice experiments, females would never chose males from the wrong species.B. This is a case of random variation within the population.C. This is a case where hybrid offspring of the two species are less fit than either of the parent species. In the geographic areas where the populations overlap, natural selection has reinforced color differences that serve as reproductive barriers between the two species.D. Hybrid offspring of the two species are more fit than either of the parent species. Eventually the two hybridizing species will fuse into one.
C. This is a case where hybrid offspring of the two species are less fit than either of the parent species. In the geographic areas where the populations overlap, natural selection has reinforced color differences that serve as reproductive barriers between the two species.
Explanation:
Nature has developed certain reproductive barriers or mechanisms of reproductive isolation. These occur to prevent members of different species from mating and producing offspring or to make sure that the offspring are sterile.
Recency effect is the belief that audience's retention of information or ideas or in short-term memory is dependent on the order of presentation. More recently acquired information are easily and well remembered to make judgement or decision than the earlier acquired information.
The correct answer to the following question will be "Values and Norms".
Explanation:
General values are ideals that determine what is right and what is wrong. Norms are laws and obligation which define how people in different social circumstances should and shouldn't act.
Norms are set guidelines of conduct and behavior guidelines, while values include principles or expectations about actions, but don't specifically state how to conduct ourselves.
