Which chromosomes have more genes​

The X chromosome is about three times larger than the Y chromosome, containing about 900 genes, while the Y chromosome has about 55 genes.

Explanation:

The X chromosome is much larger than the Y chromosome; therefore it carries substantially more active genes than the Y chromosome. Consequently, females with an XX karyotype could have higher gene expression from their two X chromosomes than males with an XY karyotype that have a single X.
