Chapter 14, Problem 5TYK
Bird guides once listed the myrtle warbler and Audubon’s warbler as distinct species that lived side by side in parts of their ranges. However, recent books show them as eastern and western forms of a single species, the yellow-rumped warbler. Most likely, it has been found that these two kinds of warblers
a. live in similar habitats and eat similar foods.
b. interbreed often in nature, and the offspring are viable and fertile.
c. are almost identical in appearance.
d. have many genes in common.

Students have asked these similar questions
When the isthmus of Panama (land bridge that connects north and south America) arose about 3 million years ago, it caused species of fish to diverge into sister species located in either the caribean or pacific ocean. Why did they form separate species?
A)
Because this is an example of sympatric speciation
B)
Because the tides are different on each side of the land bridge
C)
Because different predators in each ocean caused the populations to diverge
D)
Because the populations were reproductively isolated
The domestic dog belongs to the species Canis familiaris. The great dane, golden retriever, cocker spaniel, fox terrier and chihuahua are different breeds within this species. a List some differences between these breeds. b List some differences within one of these breeds. c Considering the differences in size between the largest and smallest of these breeds, explain how it is that they are all considered to belong to the same species.
In which situation will populations experience gene flow?
A)hybridization between two populations of ground beetles
B)natural-selection pressures between two populations of dragonflies
C)mate competition between two populations of red-legged grasshoppers
D)intersecting migration routes between two populations of monarch butterflies

- 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.arrow_forwardbased on the image attached a) Explain how genetic drift caused egg hatching to decrease in the late 1980s and 1990. b) Why did hatching improve following translocations? c) What are the general effects of gene flow between populationsarrow_forwardAll of the following are examples of prezygotic isolation except?

Two closely related species of song birds whose hybrid embryos die early in development D.)

- The three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.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_forwardIn the bighorn sheep population of North America, what would happen if all of the large-bodied, large-horned males were hunted, leaving only small-bodied, small-horned sheep? a)Males could no longer protect females from predators, so eventually all of the sheep would be eaten by predators. b)There would be no phenotypic variation in the population of sheep, and natural selection could not lead to males with larger horns in the future. C)The size of horns would no longer be a heritable traits, and would males would not pass this trait to their offspring. d)Males would begin to use their horns for other behaviors, such as hunting prey or being better competitors.arrow_forward
