Introduces variations in number of offsprings pertains:

Options

A. Asexual
B. Sexual Reproduction
C. Parthenogeneses
D. Sporulation

Answer

To solve the question "Introduces variations in number of offsprings pertains," we need to analyze the different reproductive processes mentioned: asexual reproduction, sexual reproduction, parthenogenesis, and sporulation.

### Step-by-Step Solution:

1. **Understanding Asexual Reproduction**:
- Asexual reproduction involves only one parent.
- Offspring produced are genetically identical to the parent, resulting in clones.
- There is no fusion of gametes, leading to no genetic variation among the offspring.

2. **Understanding Sexual Reproduction**:
- Sexual reproduction involves two parents.
- It includes the fusion of gametes (sperm and egg).
- This process mixes genetic material from both parents, leading to offspring that are genetically different from each other and their parents.
- This mixing of genetic information introduces variations in the offspring.

3. **Understanding Parthenogenesis**:
- Parthenogenesis is a form of asexual reproduction where an egg develops into an embryo without fertilization.
- Since there is no fusion of gametes, this process does not introduce variations in the offspring.

4. **Understanding Sporulation**:
- Sporulation is a method of reproduction where spores are produced.
- While spores can lead to new individuals, this process is also a form of asexual reproduction and does not involve genetic variation.

5. **Conclusion**:
- Among the given options, sexual reproduction is the only process that introduces variations in the number of offspring due to the genetic mixing from two parents.
- Therefore, the correct answer is **sexual reproduction**.

### Final Answer:
The process that introduces variations in the number of offspring pertains to **sexual reproduction**.
