Question
Which of the following events happen in Prophase I?
- Crossing over
- Segregation
- Independent assortment
- Cytokinesis
Hint:
The exchange of gene segments between homologous chromosomes.
The correct answer is: Crossing over
- Crossing over occurs during pachytene stage of prophase 1 of meiosis
- During crossing over, the homologous chromosomes will exchange genetic segments between themselves
- Crossing over results in gene diversity among population
