In which kind of study is banding done

Options

A. Creation of new species
B. Production of disease resistant variety
C. Mapping of chromosomes
D. Artificial pollination

Explanation

**Step-by-Step Solution:**

1. **Understanding Banding**: Banding refers to the distinct patterns observed on chromosomes when they are stained. These patterns help in identifying specific regions of chromosomes.

2. **Identifying the Context**: Banding is particularly relevant in the study of chromosomes within the nucleus of cells. It is used to visualize and identify chromosomal structures.

3. **Purpose of Banding**: The primary purpose of banding is to map genes and identify chromosomal abnormalities. This is crucial in genetics and cytogenetics.

4. **Cytogenetic Mapping**: The specific study that involves banding is known as cytogenetic mapping. This process allows scientists to determine the location of genes on chromosomes and understand their organization.

5. **Evaluating Options**: Given the options:
- Creation of new species
- Production of disease-resistant variety
- Mapping of chromosomes
- Artificial pollination

The option that directly relates to the study of banding is "mapping of chromosomes."

6. **Conclusion**: Therefore, the correct answer to the question "In which kind of study is banding done?" is **mapping of chromosomes**.
