Define the term: Linkage

Explanation

**Step-by-Step Solution:**

1. **Definition of Linkage**: Linkage refers to the tendency of DNA sequences that are located close together on a chromosome to be inherited together during the process of meiosis, which is a type of cell division involved in sexual reproduction.

2. **Mechanism of Inheritance**: During meiosis, chromosomes are segregated into gametes. If two genes are located close to each other on the same chromosome, they are less likely to be separated during this process, leading to their co-inheritance.

3. **Recombination Frequency**: The closer two genes are on a chromosome, the lower the chances of recombination occurring between them. Recombination is the process where genetic material is exchanged between homologous chromosomes, leading to genetic diversity.
