The phenotype frequency in a population changes after each generation, which would most likely be causing this? A. The population is to large. B. Mates are chosen randomly C. Some traits give an advantage. D. All organisms produce one offspring.

C. Some traits give an advantage

Explanation:

Due to evolution, some organisms tend to undergo some gradual change of characteristics that is from simple life forms to more complex life forms due to the adaptation of the organisms to the environment. These adaptations are passed to offsprings from their parents and only the organism with beneficial characteristics survive hence there is differing in phenotype frequency.
