13. Pemales of the species Drosophila males of their close relative Drosophila persimilis than they do to those species. This is an example of A) gametic isolation. B) hybrid infertility. C) behavioral isolation. D) adaptive radiation. E) sympatric speciation. psendoobscaura respond less well to the courtship signals from. of males of their own 14. The sperm of one species of sea urchin is chemically incompatible with the eggs of a closely related species. This type of reproductive isolating barrie is called A) postzygotic isolation. B) gametic isolation. C) low hybrid zygote viability. D) temporal isolation. E) Both a and b Features shared by two or more species that are inherited from the same common ancestor are A) analogous. B) aligned. C) homologous. D) coincident. E) coordinate. Despite inhabiting overlapping ranges, the western spotted skunk and the eastern spotted skunk do not interbreed. One reason for this lack of interbreeding is that the western species breeds in early fall and the eastern species breeds in late winter to early spring. This is an example of- isolation. A) chemical B) gametic C) postzygotic D) temporal E) mechanical 16. descendants is considered A group that includes the common ancestor and some, but not all, of its to be A) paraphyletic.

Cylochrome c is an important component of the respiratory chain in the mitochondria and is found in all eukaryotes. A) True B) FalseExplanation / Answer
Please find the answers below:
Answer 13: Choice C (Since the two species are different, the females do not tend to respond to the males of different species as their natural behavior, hence behavioral isolation)
Answer 14: Choice B (gametic isolation is a phenomenon by virtue of which inter-specific fertilization is naturally prevented in organisms)
Answer 15: Choice C (Homologous features such as body strucures, represent those inherited by different species but from same genetic ancestor)
Answer 16: Choice D (Temporal isolation refers to the inability to undergo fertilization due to non-synchronous presence of the male and female gametes)
