What is the primary source of genetic variation in populations? (2023)

Step 1: Understand what genetic variation means. It refers to the differences in DNA among individuals in a population.
Step 2: Learn about mutations. Mutations are changes in the DNA sequence that can occur naturally.
Step 3: Recognize that mutations can create new traits or characteristics in organisms.
Step 4: Realize that these new traits can be passed on to future generations if they occur in reproductive cells.
Step 5: Conclude that mutations are the primary source of genetic variation because they introduce new genetic material into a population.
