How many polar bodies are produced during the entire process of oogenesis in unmarried human female ?

Options

A. Three
B. Two
C. One
D. Four

Answer

To determine how many polar bodies are produced during the entire process of oogenesis in an unmarried human female, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Oogenesis**: Oogenesis is the process of egg (ovum) formation in females. It begins with the primary oocyte, which is present in the ovaries.

2. **Meiotic Division**: The primary oocyte undergoes meiosis, which consists of two meiotic divisions:
- The first meiotic division results in the formation of a secondary oocyte and the first polar body. The secondary oocyte is larger and will eventually become the ovum if fertilization occurs.
- The first polar body is a smaller cell that typically does not develop further.

3. **Completion of Meiosis**: In a typical scenario where fertilization occurs, the secondary oocyte will undergo a second meiotic division upon the entry of sperm, producing:
- A haploid ovum (the mature egg).
- A second polar body.

4. **Scenario for Unmarried Females**: In the case of an unmarried human female, there is no sperm to trigger the completion of the second meiotic division. Therefore:
- The secondary oocyte does not complete its meiotic division, and the second polar body is not formed.

5. **Final Count of Polar Bodies**: Since only the first polar body is produced and the second meiotic division does not occur:
- The total number of polar bodies produced in an unmarried human female is **one**.

### Conclusion:
The answer to the question is that **one polar body** is produced during the entire process of oogenesis in an unmarried human female.
