Members of the same species

Options

A. Produce fertile offsprings in natural condition
B. are reproductively isolated
C. differ a lot with each other
D. are genetically similar

Answer

To solve the question regarding members of the same species, we need to analyze the characteristics that define a species and the options provided. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Definition of a Species
A species is generally defined as a group of organisms that can interbreed and produce fertile offspring under natural conditions. This means that members of the same species share similar characteristics and can reproduce with one another.

**Hint:** Remember that the ability to interbreed and produce fertile offspring is a key characteristic of a species.

### Step 2: Analyze the Options
The options provided in the question are:
1. Produce fertile offspring.
2. Reproductively isolated in natural conditions.
3. Differ a lot with each other.
4. Are genetically similar.

### Step 3: Evaluate Each Option
- **Option 1: Produce fertile offspring.** This aligns with the definition of a species, as members of the same species can interbreed and produce viable offspring.

- **Option 2: Reproductively isolated in natural conditions.** This is incorrect because members of the same species are not reproductively isolated; they can mate and produce offspring.

- **Option 3: Differ a lot with each other.** This is also incorrect. While there may be variations among individuals, members of the same species share more similarities than differences.

- **Option 4: Are genetically similar.** This option is misleading. While members of the same species share a common genetic makeup, there can be genetic variation among individuals.

### Step 4: Conclusion
Based on the analysis, the correct answer is **"produce fertile offspring in natural conditions."** This option accurately reflects the defining characteristic of members of the same species.

**Final Answer:** Produce fertile offspring in natural conditions.
