Select the incorrect match

Options

A. `{:("Submetacentric"," - L shaped"),("Chromosomes","chromosomes"):}`
B. `{:("Allosomes"," - sex"),("","chromosomes"):}`
C. `{:("Lampbrush"," - Diplotene"),("chromosomes","bivalents"):}`
D. `{:("Polytene"," - Oocytes"),("chromosomes","of amphibians"):}`

Answer

To solve the question "Select the incorrect match," we will analyze each option provided and determine if the matches are correct or incorrect.

### Step-by-Step Solution:

1. **Option A: Submetacentric Chromosome - L-shaped chromosome**
- Submetacentric chromosomes have their centromeres located slightly off-center, resulting in one arm being longer than the other. This gives them an L-shaped appearance during cell division.
- **Conclusion:** This match is correct.

2. **Option B: Allosomes - 6 chromosomes**
- Allosomes, also known as sex chromosomes, are responsible for determining the sex of an organism. In humans, there are typically 2 sex chromosomes (X and Y), not 6.
- **Conclusion:** This match is incorrect.

3. **Option C: Lambrush Chromosome - Diplotene bivalents**
- Lambrush chromosomes are a type of chromosome that appears during the diplotene stage of meiosis. They are characterized by their long, looped structure, resembling bivalents.
- **Conclusion:** This match is correct.

4. **Option D: Polytene Chromosome - Oocyte of Amphibians**
- Polytene chromosomes are large chromosomes that are primarily found in the salivary glands of certain insects, such as Drosophila. They are not typically associated with the oocytes of amphibians.
- **Conclusion:** This match is incorrect.

### Final Answer:
The incorrect match is **Option B: Allosomes - 6 chromosomes** and **Option D: Polytene Chromosome - Oocyte of Amphibians**. However, since the question asks for a single incorrect match, we can highlight that **Option B** is the most clear incorrect match.
