An organism's ability to survive and reproduce is called the organism's

Question

Quizplus · Accepted Answer

Fitness refers to an organism's ability to survive and reproduce, both of which are key components of evolutionary success. Organisms with higher fitness are more likely to pass on their traits to the next generation, leading to a gradual change in the genetic makeup of a population over time. Natural selectivity (A) is not a term commonly used in biology, advantage (B) and phenotype (C) are related concepts but do not encompass the entire concept of survival and reproduction, and genotype (D) refers to an organism's genetic makeup rather than its ability to survive and reproduce.
