Question

A set of full-sibling juvenile wolf spiders was divided into two groups. One set was reared in low-temperature conditions, while the other set was reared in high-temperature conditions until they were adults. As adults, each individual was exposed to a predator at a moderate temperature and the groups exhibited very different escape behavior—those reared in low-temperature conditions fled sooner than those reared in high-temperature conditions. Which of the following can be concluded from these data?
a. Antipredator behavior exhibits a gene-environment interaction
b. Antipredator behavior is heritable
c. Antipredator behavior changes over time
d. There is an environmental influence on antipredator behavior
e. Genes and the environment affect antipredator behavior

Answer 1

Answer:

e. Genes and the environment affect antipredator behavior

Explanation:

Based on the data that was derived from the study we can conclude that Genes and the environment affect antipredator behavior. This is because regardless of the difference in the environment they were reared in both groups fled from the predator which is a genetic trait that has been passed down from generation. Yet, the group reared in low-temperature conditions fled sooner than those reared in high-temperature conditions meaning that the environment has affected the survival and antipredator behavior of the spiders.
