Write the correct sequence of genetic diversity

Options

A. Kingdom - Population - Species - Genes - Chromosome - Nucleotides
B. Species - Genes - Population - Chromosomes - Nucleotides
C. Population - species - chromosomes - Genes - Nucleotides
D. Kingdom - Species - Chromosomes - Genes - Nucleotides.

Answer

To answer the question regarding the correct sequence of genetic diversity, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding Genetic Diversity**: Genetic diversity refers to the variety of genes within a species, as well as the variety of species within a habitat. It is crucial for the survival and adaptability of organisms.

2. **Identify the Levels of Biological Organization**: The levels of biological organization relevant to genetic diversity include:
- Kingdom
- Species
- Chromosomes
- Genes
- Nucleotides

3. **Establish the Hierarchical Sequence**: The correct sequence from broadest to most specific (or from highest to lowest genetic diversity) is:
- **Kingdom**: This is the broadest category and contains a wide variety of species.
- **Species**: Within a kingdom, there are multiple species, each with its own genetic makeup.
- **Chromosomes**: Each species has a specific number of chromosomes that carry genetic information.
- **Genes**: Chromosomes are made up of genes, which are segments of DNA that code for traits.
- **Nucleotides**: Genes are composed of nucleotides, the basic building blocks of DNA.

4. **Final Sequence**: Therefore, the correct sequence of genetic diversity in decreasing order is:
- Kingdom → Species → Chromosomes → Genes → Nucleotides

5. **Conclusion**: The correct answer to the question is option number 4, which represents the hierarchical structure of genetic diversity.
