Individuals of same species having genetic variation and occur in same environment are called:–

Options

A. Biotypes
B. Ecotype
C. Ecophenes
D. Ecads

Answer

To solve the question "Individuals of the same species having genetic variation and occurring in the same environment are called:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**:
- We need to identify a term that describes individuals of the same species that have genetic variations but live in the same environment.

2. **Analyzing the Options**:
- The options provided are: Biotype, Echotype, Esophins, and Echates. We need to evaluate each term to see which one fits the description.

3. **Defining Biotype**:
- A biotype refers to a population of a species that has genetic differences. Members of a biotype can be homozygous or heterozygous and are closely related morphologically. They exist in the same environmental conditions.

4. **Defining Ecotype**:
- An ecotype refers to members of a species that show the same genetic response to a particular habitat. This means that while they are genetically similar, they are adapted to specific environmental conditions.

5. **Defining Esophins and Echids**:
- Esophins and Echids refer to individuals of a species that exhibit different phenotypes due to varying environmental conditions. This means they do not fit our criteria since they are affected by different environments.

6. **Conclusion**:
- Since we are looking for individuals of the same species with genetic variation in the same environment, the correct answer is **Biotype**.

### Final Answer:
- Individuals of the same species having genetic variation and occurring in the same environment are called **Biotypes**.
