Which of the following is a source of genetic variation in a population? (2000)

Step 1: Understand what genetic variation means. It refers to the differences in DNA among individuals in a population.
Step 2: Identify sources of genetic variation. Two main sources are mutation and gene flow.
Step 3: Learn about mutation. A mutation is a change in the DNA sequence that can create new traits.
Step 4: Understand gene flow. Gene flow is the movement of genes between populations, which can introduce new genetic material.
Step 5: Recognize that both mutation and gene flow are important for evolution because they provide new genetic combinations.
