Maximum number of gene present on which chromosome number in human.

Options

A. 1st
B. X
C. Y
D. 10th

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which chromosome in humans contains the maximum number of genes.

2. **Human Genome Project**: The answer to this question is derived from the findings of the Human Genome Project, which was a significant research initiative aimed at mapping all the genes in the human genome.

3. **Duration of the Project**: The Human Genome Project lasted for 13 years, starting in the early 1990s and concluding in May 2006.

4. **Findings of the Project**: The project revealed that the human genome consists of approximately 3,164.7 million nucleotide bases and contains a vast number of genes.

5. **Average Gene Size**: It was found that the average gene is made up of about 3,000 nucleotide bases.

6. **Largest Known Human Gene**: The largest known human gene is dystrophin, which spans about 2.4 million bases.

7. **Chromosome Gene Count**: Among all the chromosomes, chromosome number 1 has the highest number of genes, totaling 2,968.

8. **Comparison with Other Chromosomes**: In contrast, the Y chromosome has the fewest genes, with only 231 genes, making it the smallest chromosome in terms of gene count.

9. **Conclusion**: Therefore, the chromosome with the maximum number of genes in humans is chromosome number 1.

**Final Answer**: Chromosome number 1 has the maximum number of genes in humans.
