Step by step
Solved in 3 steps
- During mating season, male rams compete with each other for access to females. This describes Group of answer choices intersexual selection intrasexual selection the direct benefits model Hamilton-Zuk hypothesis Fisherian sexual selectionSome bird species mate monogamously for life (i.e., individuals keep the same partner year after year). Other bird species are seasonally monogamous: they choose a new mate every year. Some bird species have what is called helpers-at-the-nest; these helpers are older offspring who stick around and assist their parents in taking care of babies born the next year. Kin selection would predict that you would find more instances of helpers-at-the-nest in the species that mate monogamously for life than in the seasonally monogamous species. Why? Be sure to address why they might still help in seasonally monogamous pairs.Sexual selection is kind of natural selection in which characteristics related to mating success are the targets of selection. male features are always the key characteristics selected. competition among individuals of the same sex is always involved. infertility is the most common problem. All of the choices are correct.

- Match the scenario to the type of sexual selection: Question 10 male parrots wish to mate with a female. The female chooses to mate with the male that has the brightest tail feathers. Male giraffes perform mating dances. The ones that perform the dance better are chosen by the female as a mate. Male kangaroos fight each other, the winner claims the female to mate with. Male red-winged blackbird sing and display their feathers to establish their territories. All of the females in that territory will exclusively mate with that male. The impressive feathers of a male peacock are the result of this type of sexual selection All Answer Choices A. Intrasexual selection B. Intersexual selectionAccording to proponents of behavioral ecology, Group of answer choices infanticide is beneficial for the social group individuals consciously behave in ways that ensure their fitness individuals act to enhance the survival of their species Individuals choose certain environments based upon the likelihood of carrying out aggressive behavior behaviors have evolved through the operation of natural selectionWhich of these interactions are examples of sexual selection? Select all that apply. A change in food resources on an island favors finches with medium-sized beaks. Finches with small and large beaks disappear from the island after a few generations. Female flies prefer to mate with males that have longer eyestalks. These eyestalks provide no survival advantage, but longer eyestalks become more common over generations. Male seals compete for territory and access to clusters of female seals. The more aggressive male seals tend to secure the largest territories and clusters.
- In one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.Which of the following is true of a peacock's tail: It is a result of intersexual selection It is an example of sexual dimorphism in the species It is a result of intrasexual selection all of the aboveWhat is the nature of the reproductive barrier between a species that mates at dawn (sunrise) and a species that mates at dusk (sunset)? gametic temporal habitat behavioral mechanical One insect species mates on goldenrod flowers, while a second species mates on autumn daisies. The two species are mechanically compatible and the flowers bloom at the same time, but the insects do not interbreed. This is an example of __________ isolation. temporal habitat gametic mechanical behavioral
