What is the name of the process by which genetic material is shuffled during meiosis, increasing genetic variation?
Correct answer: C. Crossing over
- A. Mutation
- B. Genetic drift
- C. Crossing over
- D. Gene flow
Explanation
Crossing over is the process by which segments of DNA are exchanged between homologous chromosomes during meiosis, resulting in increased genetic variation.

About Gene Linkage and Crossing Over
Linked genes lie on the same chromosome and tend to pass together, unlike genes that assort independently on different chromosomes. The topic connects linkage with homologous pairing, crossing over during prophase I of meiosis, recombinant and parental offspring, and recombination frequency as an estimate of gene distance.
