### Step-by-Step Solution: 1. **Understanding Disjunction**: Disjunction refers to the process where homologous chromosomes are separated from each other during cell division. This is a crucial step in ensuring that each daughter cell receives the correct number of chromosomes. 2. **Identifying the Phases of Cell Division**: There are two main types of cell division relevant to this question: Meiosis and Mitosis. In meiosis, there are two divisions: Meiosis I and Meiosis II, each consisting of several phases including prophase, metaphase, anaphase, and telophase. 3. **Focus on Anaphase I**: During Anaphase I of meiosis, homologous chromosomes (each consisting of two sister chromatids) are pulled apart and move towards opposite poles of the cell. This separation is what is referred to as disjunction. ...
