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 brings about random mixing of genetic material.
The correct answer is: It creates genetic diversity
- Crossing over occurs during prophase 1 of meiosis
- During crossing over, the homologous chromosomes will exchange chromosomal segments between one another. As a result, random mixing of genetic material occurs.
- As a result of mixing of genetic material, genetic diversity is created, making the offspring unique among the rest of the population
