Species is a

Options

A. Closely related interbreeding population
B. Closely related non-breeding population
C. Taxonomic genera of same species
D. none

Answer

**Step-by-Step Solution:**

1. **Understanding the Definition of Species**: A species is defined as a group of organisms that are closely related and can interbreed, producing fertile offspring. This means that members of the same species share similar characteristics and genetic makeup.

2. **Analyzing the Options**:
- **Option 1**: "Closely related interbreeding population" - This aligns with the biological definition of a species.
- **Option 2**: "Closely related non-breeding population" - This does not fit the definition since non-breeding populations cannot be classified as a species.
- **Option 3**: "Taxonomic genera of same species" - This option is misleading because genera encompass multiple species, not just one.
- **Option 4**: "None of the above" - This option is incorrect as option 1 is valid.

3. **Conclusion**: Based on the analysis, the correct answer is the first option, which states that a species is a "closely related interbreeding population."

4. **Additional Information**: The concept of species is also important in the context of binomial nomenclature, where the first part of the name represents the genus and the second part represents the specific name of the species.

5. **Understanding Speciation**: The process by which new distinct species arise from evolutionary changes is called speciation.

**Final Answer**: The correct answer is: **Closely related interbreeding population.**
