### Mendel's Second Law (Independent Assortment) Activity

**Question:**

Mendel's second law (independent assortment) has its basis in which of the following?

1. ○ Alignment of homolog pairs at the equator
2. ○ Separation of homologs at anaphase
3. ○ Separation of cells at telophase
4. ○ Crossing over

Please select the correct option to understand the principle underlying Mendel's second law of independent assortment and its connection to meiosis. Here are some key points related to each choice to help guide your understanding:

1. **Alignment of homolog pairs at the equator:**
    - This occurs during metaphase I of meiosis.
    - Homologous chromosomes line up randomly at the cell's equatorial plane.

2. **Separation of homologs at anaphase:**
    - This occurs during anaphase I of meiosis.
    - Homologous chromosomes are pulled apart to opposite poles of the cell.
    
3. **Separation of cells at telophase:**
    - This involves the final separation of the cells, resulting in two new cells at the end of meiosis I and II.
    
4. **Crossing over:**
    - This occurs during prophase I of meiosis.
    - Homologous chromosomes exchange segments to increase genetic diversity.

Understanding Mendel's second law helps in comprehending how traits are inherited independently of each other, contributing to genetic variation.
