2. Male dragonflies of one species are unable to grasp the abdomen of female dragonflies of a different species securely enough to mate, due to poor alignment of the four wings on each insect. This type of interference during mating attempts between different dragonfly species is: A. an example of a pre-zygotic barrier due to behavioral isolation B. an example of a pre-zygotic barrier due to C. an example of a pre-zygotic barrier due to mechanical isolation D. an example of alpre-zygotic barrier due to habitat isolation E. an example of a pre-zygotic barrier due to temporal isolation gamete isolation

2) The more impressive the tail of a male peacock, the higher its chances of finding a mate. Female peacocks choose mates based on the color of the feathers and the overall physical prowess of the animal. However, a genetic mutation called leucism can produce a peacock with only white feathers. This mutation causes the inability of pigment to be deposited into their feathers which results in a white appearance. What would you infer to be the fitness of the white peacock? Choose ALL that apply. A) The females will equally choose the brightly colored and white peacocks as mates. Eliminate B) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, making them desirable mates. C) If females choose the brightest males as partners, the ones without the impressive tails will be less likely to mate and reproduce. D) White peacocks are highly prized, thought to symbolize purity, eternity, and unconditional love, causing them to…
6. All of the following statements about mating behavior are correct except: Intersexual selection describes females choosing males based on traits that indicate superior fitness compared to other males intrasexual selection results in selection for traits that help a male be superior in competition with other males the mating relationships of most birds appear monogamous from behavioral observations the mating relationships of most mammals are monogamous to ensure reproductive success of the pair polygamous relationships most often involve a single male and many females, but in some species that is reversed.

#1: Elephant Seals have a polygynous mating system, in which a few males mate with many females while other males do not mate at all. Nearly all females produce one offspring per year. Assuming a 50:50 sex ratio, we would expect the average reproductive rate to be (chose one answer) a. higher in females b. the same in males and females c. higher in males d. random e. none of the above

1.What does a male cricket need to be able to reproduce? 2. Is calling good or bad for a cricket's fitness? 3. Give some examples of selection at work in this cricket story. 4. How does selection favor calling? (When is calling a good thing?) a) How does selection favor not calling? (When is not calling a good thing?)
Think back to Section 44.6. When researchers moved guppies from populations preyed on by cichlids to a habitat with killifish, the life histories of the transplanted guppies evolved. They came to resemble those of guppy populations preyed on by killifish. Males became gaudier; some scales formed larger, more colorful spots. How might a decrease in predation pressure on sexually mature fish allow this change?

Explain why the behavior is likely or unlikely to evolve between a non-queen female wasp and her brother.
