In biological terminoligy, a group of similar organisms which are capable of interbreeding and producing fertile which are capable of interbreeding and producing fertile offsprings is called

Options

A. species
B. genus
C. tribe
D. family.

Answer

To solve the question, we need to identify the biological term that describes a group of similar organisms capable of interbreeding and producing fertile offspring. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Question
The question asks for a specific biological term that defines a group of similar organisms that can interbreed and produce fertile offspring.

### Step 2: Recall Taxonomy
In biology, organisms are classified into a hierarchy known as taxonomy. This classification ranges from broad categories (like kingdom) to very specific ones (like species).

### Step 3: Define Key Terms
- **Interbreeding**: This refers to the ability of organisms to mate and produce offspring.
- **Fertile Offspring**: This means that the offspring produced can also reproduce.

### Step 4: Identify the Group
The group of organisms that share these characteristics (similarity, ability to interbreed, and produce fertile offspring) is known as a **species**.

### Step 5: Reference to Biological Definitions
The concept of species is often defined in biology by Ernst Mayr, who emphasized that a species is a group of organisms that can interbreed and produce fertile offspring.

### Conclusion
Based on the understanding of the question and the definitions provided, the answer is:
**Species**
