Textbook Question
Chapter 14, Problem 11TYK
When hybrids produced in a hybrid zone can breed with each other and with both parent species, and they survive and reproduce as well as members of the parent species, one would predict that
a. the hybrid zone would be stable.
b. sympatric
c. reinforcement of reproductive barriers would keep the parent species separate.
d. reproductive barriers would lessen and the two parent species would fuse.

Which of the following is an example of postzygotic reproductive isolation?a. Sperm of species A dies in the oviduct of species B before fertilization can take place.b. Hybrid zygotes between species A and B are spontaneously aborted early indevelopment.c. The mating seasons of species A and B do not overlap.d. Males of species A are not attracted to the pheromones produced by the females ofspecies B.
Problems with the biological species concept include the fact that
a. many species reproduce asexually.
b. postzygotic isolating mechanisms decrease hybrid viability.
c. prezygotic isolating mechanisms are extremely rare.
d. All of the choices are correct.
Which of the following would be a good example of premating reproductive isolation?
A. Cross-fertilizations between the gray treefrogs, Hyla versicolor and H. chrysoscelis result in a high degree of mortality prior to hatching of hybrid eggs.
B. The mule, a hybrid between horses and donkeys is viable, but sterile.
C. Males of H. versicolor produce an advertisement call with a much slower pulse rate than males of H. chrysoscelis and females use pulse rate differences to avoid mating with the wrong species.
D. Hybrid offspring are produced from matings between leopard frogs and green frogs, but usually die before the tadpoles metamorphose into froglets.

- 1) In allopatric speciation, geographic separation of two populations a.reduces the relative fitness of hybrid offspring. b.is sufficient for speciation to occur. c.allows gene flow between them. d.inhibits gene flow between them.arrow_forwardWhich of the following is not an event that can contribute to allopatric speciation? a. A mountain range forms and splits two populations into populations that begin to turn into new species. b. A subset of individuals disperse to a far away island and begin to turn into a new species. c. Two populations breed in the same location but at different times, and therefore begin to turn into two new species. d. A river splits a population into two populations and the two populations begin to diverge on either side of the river. e. All of these are potential contributors to allopatric speciation.arrow_forwardWhich of the following is NOT true for the speciation of finches in the Galapagos islands? A. Natural selection acted on beak shape, and resulted in different beak morphologies for different food sources. B. Assortative mating reinforced existing divergence between birds. C. Speciation of finches started by birds starting to specialize on different food sources. D. Speciation of finches on the same island is due to allopatric speciation.arrow_forward
- A mountain range divides a freshwater snail species into two large isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of: O A. allopatric speciation by vicariance. O B. sympatric speciation. C. parapatric speciation. D. allopatric speciation by peripheral isolation. « » A Moving to another question will save this response. 8:02 AM 11/10/20 a 18 hp 近arrow_forwardTwo parents, who are thought to be different species, mate and produce viable hybrid offspring. When two of these hybrids mate, their offspring are not viable. What is the BEST interpretation of this data? A. The original parents are the same species because they can breed together. B. The original parents are the same species because they can breed together and produce viable offspring. C. The original parents are not the same species because they produce hybrids that impair the species’ development or survival in its environment. D. The original parents are not the same species because they produce hybrids that can have reduced viability and fertility when they mate.arrow_forwardWhich of the following statements is false? a. Gradual speciation is most likely to occur in a large population that lives in a stable climate. b. Punctuated equilibrium is unlikely to occur in a large population that lives in a stable climate. c. Gradual speciation and punctuated equilibrium both result in the divergence of species. d. Gradual speciation is most likely to occur in a small population that experiences a rapid change in its environment.arrow_forward
