The phenotype frequency in a population, changes after each generation. which would most likely be causing this?
a) random mating
b) a lack of mutation
c) an infinitely large population
d) competition between organisms

D) Competition between organisms

Explanation:

Random mating between organisms, absence of any factor of evolution (mutation, recombination, gene flow, migration etc.) and a large population size serve to maintain the allele frequency and thereby the phenotype frequency over generations. However, competition between organisms for any natural resource leads to natural selection of "better competing organisms" and increases their phenotype frequency in the population.

D. Competition between organisms

Explanation:

Have a great day :)
