Bivalent

Explanation

### Step-by-Step Solution:

1. **Definition of Bivalent**: A bivalent is a structure formed during the process of meiosis, specifically during prophase I. It consists of a pair of homologous chromosomes.

2. **Understanding Homologous Chromosomes**: Homologous chromosomes are pairs of chromosomes that consist of one chromosome from the mother and one from the father. They have the same genes at the same loci but may have different alleles.

3. **Formation of Bivalent**: The bivalent is formed when homologous chromosomes align with each other during meiosis. This pairing is crucial for the process of genetic recombination, which occurs through crossing over.
