What happens in prophase I of meiosis?

What happens in prophase I of meiosis?
  1. Homologous chromosomes move to the opposite poles
  2. Bivalents arrange on the equatorial plate
  3. Homologous chromosomes pair to form bivalents and undergo crossing over
  4. Sister chromatids separate

Solution

Prophase I is the longest phase in meiosis I. During this phase, homologous chromosomes pair to form bivalents and undergo crossing over, which leads to the exchange of genetic material between the chromosomes.
