Question
Which of the following events happen in Prophase I?
- Crossing over
- Segregation
- Independent assortment
- Cytokinesis
Hint:
The exchange of chromosomal 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 segments with each other.
- Exchange of chromosomal segments will produce recombinant or a hybrid chromosome.
- Crossing over produces random mixing of genetic material during gametogenesis.
