Asked by yo mama
An enlarged right ventricle both increases oxygen intake and the risk of pulmonary hypertension. How can natural selection result in an adaption that produces both positive and negative effects?(1 point)
Responses
The positive effects outweigh the negative effects in certain environments.
The positive effects outweigh the negative effects in certain environments.
The positive effects appear after reproductive age in certain environments.
The positive effects appear after reproductive age in certain environments.
The negative effects appear before reproductive age in certain environments.
The negative effects appear before reproductive age in certain environments.
The negative effects appear later in life in certain environments.

Natural selection favors traits that increase reproductive success; if the enlarged right ventricle improves oxygen intake (and thus early-life fitness) but causes pulmonary hypertension only after reproductive age, the net fitness effect can be positive and the trait will persist.
