**Step-by-Step Solution:** 1. **Understanding Meiosis**: Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of gametes (sperm and eggs). It is often referred to as reductional division. 2. **Homologous Chromosomes**: During meiosis, homologous chromosomes (one from each parent) pair up. This pairing is crucial for the exchange of genetic material. 3. **Synapsis**: The process where homologous chromosomes align closely together is known as synapsis. This occurs during prophase I of meiosis. ...
