Question
Crossing over is important because
- It creates genetic diversity
- It prevents mutation
- It allows even distribution of chromosomes
- It creates genetic uniformity
Hint:
Crossing over results in recombination.
The correct answer is: It creates genetic diversity
- Crossing over occurs during the prophase 1 of meiosis.
- During crossing over the non-sister chromatids exchange segments of genetic material between them, resulting in recombination.
- Crossing over produces gametes with new combinations of genes, which produce offsprings that are different from the parents.
