Answer:
Fitness or aptitude
Explanation:
Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.
