o mutation
o crossing over
o replication
o duplication

Explanation:

• Mutation is a change in the DNA sequence, not an exchange of genetic material between chromosomes.
• Crossing over occurs during meiosis when homologous chromosomes exchange genetic material, which is what the question describes.
• Replication is the process of making a copy of DNA.
• Duplication refers to having an extra copy of a segment of DNA, not an exchange.

B. Crossing over
