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

7. Complete the following table, which compares the different reproductive barrier mechanisms. Description with example Behavioral isolation Mating time Habitat isolation Mechanical incompatibility Gametic incompatibility Hybrid weakness
A. In terms of the barriers in place that keep species separate, explain whether song recognition is a prezygotic barrier or a post-zygotic barrier. B. Explain which type of isolating mechanism this wouldbe once you determine the barrier type. C. Discuss why song would be a barrier to mating with another species and having the incorrect song might change your fitness potential.
1. Sea urchins are broadcast spawners that release clouds of sperm/eggs into the water column. However, the ability to successfully fertilize the egg by the sperm is restricted to very specific gametic proteins that inhibit cross species fertilization. This is an example of a a.

1. The benefit of fighting for a territory is 12 reproductive units, and the cost is 8 reproductive units. Should you be hawk or dove? b. The benefit of fighting for a territory is 12 reproductive units, and the cost is 8 reproductive units. What is your benefit if you play hawk and your opponent plays dove?

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.
Behavioral isolation is considered which type of reproductive barrier? a prezygotic b postzygotic c overlapping d heritable

19. In this question and the next, pretend you are studying mating behaviors in a variety of voles, including prairie voles and montane voles. In both questions, use the diagram and graphs below when determining your answer. You are using the same behavioral assay described in class, which provides a measure of the amount of time spent in each of three chambers: a chamber with a previous sexual partner (Partner chamber), a neutral chamber with no other animal (Neutral chamber), and a chamber with an unfamiliar vole (Stranger chamber). Data is expressed as percentage of time spent in each of the three chambers. First, you decide to study the effects of vasopressin receptor blockers (antagonists) on mating behavior in male prairie voles. If you apply these drugs prior to all incidents of sexual behavior involving these voles, what do you expect to observe in your three-chamber assay? Select the letter corresponding to the graph that best matches your predictions.

All of the following scenarios are examples of barriers that distinguish separate species. Which is not a post-zygotic barrier? Two species of ladybugs live in the same habitat. Although they mate at the same time of year, their genitals are physically incompatible. Two species of fish inhabit the same stream. They are capable of mating and producing healthy offspring. The offspring, however, are infertile. and 2 Two species of opossums inhabit the same forest. Although they are capable of mating, no offspring ever survive development. hschool 3, Two species of mice coexist in a forest habitat. They are capable of mating and producing offspring. The offspring, however, are frail and die young. When Charles Darwin visited the Galapagos Islands, he observed the marine iguana. He later decided that the marine iguana evolved from the terrestrial iguana found on the mainland of South America. The marine iguana differs from the terrestrial iguana in several ways. The marine iguana has a flat…
#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.
