Select the incorrect match.

Options

A. a) Lampbrush chromosomes - Diplotene bivalents
B. b) Allosomes - Sex chromosomes
C. c) Submetacentric chromosomes - L-shaped chromosomes
D. d) Polytene chromosomes - Oocytes of amphibians

Answer

To solve the question of selecting the incorrect match from the provided options, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Option A: Lambda's chromosome found in the protein bivalent.**
- **Analysis:** Lambda chromosomes are indeed found in the bivalent stage during the diplotene phase of meiotic prophase I. These chromosomes are characteristic of certain organisms, particularly amphibians. Therefore, this option is **correct**.

2. **Option B: Allosomes are sex chromosomes.**
- **Analysis:** Allosomes are indeed synonymous with sex chromosomes. They are responsible for determining the sex of an organism, distinguishing them from autosomes, which are non-sex chromosomes. Thus, this option is **correct**.

3. **Option C: Submetacentric chromosome, L-shaped chromosome.**
- **Analysis:** Submetacentric chromosomes have their centromeres located slightly off-center, resulting in one arm being longer than the other. This shape can be described as L-shaped. Therefore, this option is **correct**.

4. **Option D: Polytene chromosome, oocyte of amphibian.**
- **Analysis:** Polytene chromosomes are large, banded chromosomes that are typically found in certain organisms, such as the fruit fly (Drosophila), and are formed from repeated rounds of DNA replication without cell division. They are not found in amphibian oocytes. Therefore, this option is **incorrect**.

### Conclusion:
The incorrect match is **Option D: Polytene chromosome, oocyte of amphibian**.
