How does competition influence natural selection? Is the presence of competitors a selective force?

In a savanna ecosystem, scientists investigate a species of antelope. Male antelopes display elaborate horns, which are used in ritualized combat during the mating season. Females are observed to choose mates with larger and more symmetrical horns. Which hypothesis suggests that the preference for males with larger and more symmetrical horns is based on the direct correlation between horn size and the male's overall physical condition? Group of answer choices Runaway sexual selection Good health hypothesis Good DNA hypothesis Sexy son hypothesis

whats inductive environment and whats selective environment? can you provide an example of each?

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.

Explain how artificial selection is like natural selection

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.

Give examples of the three types of natural selection.

Which of the following are equivalent ways to talk about an allele or genotype of individuals who are able to leave MORE offspring than others in a certain environment? Check all that apply. Group of answer choices A-"has a benefit"   B-"has a higher fitness"   C-"confers a selective disadvantage"   D-"confers a selective advantage"   E-"has a cost"

Explain frequency-dependent selection in your own words.

Which of the following is true about natural selection? a) It always results in the evolution of new traits b) It always results in the strongest individuals surviving c) It always results in the fittest individuals reproducing d) It always results in the best-adapted individuals surviving
