Which of the following is a source of genetic variation? (1937)

Which of the following is a source of genetic variation? (1937)

Step 1: Understand what genetic variation means. It refers to the differences in DNA among individuals in a population.
Step 2: Identify the sources of genetic variation. The options given are mutation, gene flow, and sexual reproduction.
Step 3: Learn about mutation. This is a change in the DNA sequence that can create new traits.
Step 4: Understand gene flow. This is the movement of genes between populations, which can introduce new genetic material.
Step 5: Recognize sexual reproduction. This process combines genes from two parents, creating unique combinations in offspring.
Step 6: Conclude that all three options (mutation, gene flow, and sexual reproduction) contribute to genetic variation.
