Which of these interactions are examples of sexual selection? *Pick All Green butterflies are less likely to be eaten than yellow butterflies due to their color. Green butterflies become more numerous than yellow butterflies in the population. 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. 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.

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.
Which of the following is the best description of sexual selection? a. Sexual selection is the differential reproductive success due to variation in acquiring immunity from mates. b. Sexual selection is the differential reproductive success due to variation in survival from social selection. c. Sexual selection is the differential reproductive success due to variation in acquiring mates or mating success. d. Sexual selection is the differential survival success due to variation in avoiding mates or mating success.
Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.
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 selection
Kin Selection - Ground squirrels will often give a warning call when they see a predator, altering the other ground squirrels to the danger. Calling behavior draws attention to the calling squirrel. This being the case, why would natural selection favor this altruistic behavior? Consider this - female squirrels are 70% more likely to make a warning call than male squirrels. Also consider, male squirrels leave the colony when they reach maturity, while female squirrels stay in the colony they are born in. Explain how natural selection is working here!
Intrasexual selection involves competition among one sex (typically males) for mating access to the other sex. Intersexual selection involves mate choice in which individuals from one sex (typically females) choose their mates from among individuals of the other sex. Imagine a group of males that is engaged in agonistic behavior, from which Male A emerges triumphant. Now imagine a female that is assessing all of the males that were involved in the fights, and chooses Male A. Explain why this situation shows how intrasexual and intersexual selection pressures are likely both at play in the trait selection.
Which of the following contribute to keeping low-fitness alleles in our gene pool? Choose all that are correct Random mating Efficient selection against rare recessive disease-causing alleles New mutations Late age of onset of some diseases Inefficient selection against rare recessive disease-causing alleles
Some 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.
