Answer 1

Answer:

beneficial mutation

Explanation:

A mutation is any alteration in the genetic material of an organism. In general, mutations have a negative impact on the fitness (or reproductive success) of the individual that carries this mutation; however, there are situations where a mutation may be beneficial for the individual in a given environment. When a beneficial mutation occurs in the germline, it potentially can be passed to the next generation and progressively increases its frequency in the population.
