Fill in the blanks:
Genetic recombination from crossing over between `"________"` chromatids of chromosome.

Explanation

**Step-by-Step Text Solution:**

1. **Understanding Genetic Recombination**: Genetic recombination refers to the process by which genetic material is exchanged between chromosomes during meiosis, leading to genetic diversity.

2. **Identifying the Process of Crossing Over**: The specific mechanism of genetic recombination that occurs during meiosis is called crossing over. This occurs during prophase I of meiosis.

3. **Defining Chromatids**: Chromatids are the two identical halves of a replicated chromosome. When a chromosome is replicated, it consists of two sister chromatids.
