Question

Which chromosome in the human genome has the highest number of genes?

Options

• Chromosome X

• Chromosome Y

• Chromosome 1

• Chromosome 10

Answer 1

Chromosome 1

Explanation:

The largest and most gene-rich chromosome in the human genome is chromosome 1. It has more than 2,000 genes that code for different proteins involved in vital biological processes. On the other hand, chromosomes like X and Y contain fewer genes and are smaller, with Y having the fewest genes because of its lower genetic load. The Y chromosome has the fewest genes (231), while chromosome 1 has the most (2968).
