Summary Introduction

To explain: The reason why synapsis and crossing over cannot occur in prophase II.

Introduction: Meiosis is a process that involves two cell divisions—meiosis I and meiosis II, resulting in four daughter cells that are haploid. At prophase I, the homologous chromosomes pair with each other, and the process is known as synapsis. At the end of meiosis I, the two homologs separate into two daughter cells. The sister chromatids separate to form four haploid daughter cells in meiosis II.
