Homework Answers
Answer: Option 1. Crossing over.
Explanation: The main turn of events that occur in Prophase I of Meiosis I are:
- Condensation of chromosomes from chromatin
- Synapsis of homologous chromosomes
- Crossing over takes place
- Nuclear envelop dissolves
- Appearance of centrioles
- Formation of mitotic spindle
The main events that occur in Prophase of Mitosis are:
- Condensation of chromosomes from chromatin
- Nuclear envelop dissolves
- Appearance of centrioles
- Formation of mitotic spindle and disappearance of nucleolus.
Crossing over is the exchange of alleles between the chromosomes. In mitosis, sister chromatids are identical and homologous chromosomes do not cross over. Thus, the event of crossing over is not present in prophase of Mitosis. But in prophase I, crossing over occurs as non sister chromatids are involved.
