The nucler structure observed by Hanking 50% of the insect sperms after spermatogenesis was

Options

A. X-body
B. Autosome
C. Y-chromosome
D. Nucleolus

Answer

To solve the question regarding the nuclear structure observed by Hankings in 50% of insect sperm after spermatogenesis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question refers to the findings of Hankings, who studied the nuclear structures in insect sperm during spermatogenesis.

2. **Identify the Key Term**: The term "X body" is crucial here. Hankings discovered that in the sperm of certain insects, 50% contained a structure he termed the "X body."

3. **Clarify the Findings**: Hankings observed that in the sperm, half had the X body while the other half did not. This led to the conclusion that the X body corresponds to the X chromosome.

4. **Differentiate Between Options**:
- **X body**: This is the structure observed in 50% of the sperm.
- **Y chromosome**: This is a different chromosome that is present in males but does not correspond to the X body.
- **Autosomes**: These are non-sex chromosomes and are not relevant to the question.
- **Nucleolus**: This is a structure within the nucleus and does not pertain to the question.

5. **Conclude the Answer**: Based on Hankings' findings, the correct answer to the question is the "X body," which corresponds to the X chromosome in the sperm.

### Final Answer:
The nuclear structure observed by Hankings in 50% of the insect sperm after spermatogenesis was the **X body**.
