Branch of biology dealing with heredity and variation is

Options

A. Ecology
B. Evolution
C. Palaeontology
D. Genetics

Answer

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

1. **Understanding the Question:**
The question asks for the branch of biology that deals with heredity and variation.

2. **Analyzing the Options:**
We are provided with four options:
- Ecology
- Evolution
- Palaeontology
- Genetics

3. **Evaluating Each Option:**
- **Ecology:** This is the study of organisms and their interactions with the environment. It does not specifically deal with heredity or variation. Therefore, this option is incorrect.

- **Evolution:** This refers to the gradual process of change and development in organisms over time. While evolution can involve genetic changes, it is not specifically focused on heredity and variation. Thus, this option is also incorrect.

- **Palaeontology:** This is the study of the history of life on Earth through fossils. It does not focus on heredity or genetic variation, making this option incorrect as well.

- **Genetics:** This is the branch of biology that specifically studies genes, genetic variation, and heredity in organisms. It directly addresses the concepts of heredity and variation, making it the correct answer.

4. **Conclusion:**
The correct answer to the question is **Genetics**, as it is the branch of biology that deals with heredity and variation.
