Question

Quizplus · Accepted Answer

Mutations are the primary source for new, unique genes in a population. Mutations are random changes in the DNA sequence that can result in novel traits or characteristics. These mutations can be beneficial, neutral, or harmful and can contribute to genetic diversity in a population. Natural selection, artificial selection, and crossing over can all influence the frequency of existing genes in a population, but they are not sources for new genes.
