Question
When does crossing over occur in meiosis?
Metaphase I
Prophase I
Anaphase II
Prophase II
Metaphase I
Prophase I
Anaphase II
Prophase II
Hint:
Crossing over takes place in the first stage of meiosis.
The correct answer is: Prophase I
- The first meiosis, meiosis I, begins in prophase I.
- In prophase, I, a complex of DNA and proteins known as chromatin condenses to form chromosomes.
- Duplicated pairs of chromosomes, known as sister chromatids, remain connected at a central point called the centromere.
