Answer) Two species cannot mate with each other because they are allopatric, this form of reproductive isolation is ecological.
Allopatric speciation occurs when a population is separated geographically; for example, by an isthmus splitting an ocean or fruit flies being separated in the lab. Then the populations on both sides of the barrier cannot mate with each other, and each population evolves separately.

For each description of reproductive isolation, select the option that best describes it. Two species of orchids have different floral anatomy. [ Choose ] gametic isolation habitat isolation behavioral isolation mechanical isolation temporal isolation One species of Drosophilia breed in early morning, another species of Drosophilia breed in the afternoon. [ Choose ] gametic isolation ...
QUESTION 5 Which type of reproductive isolation mechanism is most closely related to allopatric speciation? O a mechanical O b. ecological Ocgenetic O d. temporal O e. behavioral
Required information For each of the questions in this series, determine which reproductive barrier each situation describes. Then, determine if the reproductive barrier is a form of prezygotic or postzygotic reproductive isolation. Click on the box in the table that matches both criteria. For example, if you think the situation describes behavioral isolation, and you think behavioral isolation is a postzygotic reproductive barrier, then your answer should appear as below: Prezygotic barrier Postzygotic barrier Habitat isolation Temporal isolation Behavioral isolation...
8. Evolution that results in the formation of new species is: a. Slow Evolution b. Microevolution c. Macroevolution d. True Evolution Questions 11 to 15: Match the type of reproductive isolation with its definition (answers will only be used once). a. Ecological b. Temporal c. Behavioral d. Mechanical e. Gamete 9. If two species that can mate are not attracted to each other because of differences in their courtship rituals. mate. 10. If two species inhabit the same area but...
Two closely related species have different niches. What reproductive barrier is possible? mechanical,behavioral,temporal,habitat, or gametic
NTRODUCTION Under nearly all circumstances, postzygotic reproductive isolation cannot evolve under the direct action of natural selection. Instead, postzygotic isolation evolves as a by-product of other genetic changes as proto-species diverge. In contrast, natural selection can directly act to enhance prezygotic reproductive isolation. Consider two species with overlapping ranges. If hybrids between the species are less fit than pure species individuals, females that mated with heterospecific males would be at a selective disadvantage, because their resulting offspring had low fitness....
Male call from population 1 Male call from population 2 Number of calls approached first Females from population 1 Females from population 2 species of frog has two allopatric populations separated by a deep canyon. The populations have been isolated from each other for at least 10 000 years. For her thesis, a student interested in reproductive isolation performed a mate choice experiment in which she put a female frog between two speakers. One speaker played the call of a...
Two species interbreed occasionally and produce vigorous, fertile hybrids. When the hybrids breed with each other or with either parent species, however, the offspring are feeble or sterile. These species are affected by a) gametic isolation. b) reduced hybrid fertility. c) reduced hybrid viability. d) hybrid breakdown.
ter 7 HW wing Key Concepts: Reproductive Barriers ip 1. Some closely related species of snails cannot mate because their shells spiral in opposite directions, making it impossible for their reproductive organs to be aligned. 2. Although some closely related (but separate) species of salamander can mate with each other to produce offspring, the offspring fail to develop normally and cannot reproduce. hybrid 3. In North America, one species of garter snake lives primarily in the water, while another species...
Because water molecules can form a variety of hydrogen bonds with each other, water molecules tend to have more configurations when they are by themselves than when they are mixed with other molecules that cannot form hydrogen bonds. Imagine that the interactions between water molecules and the molecules of a non polar substance A (W-A interactions) are stronger than the W-W and A-A interactions. In this case one can predict that: Water Properties Homework. Unanswered Because water molecules can form...
