Human Chromosomes and Genes
... As you can see from Figure 1.1 and Figure 1.2, the X chromosome is much larger than the Y chromosome. The X chromosome has about 2,000 genes, whereas the Y chromosome has fewer than 100, none of which are essential to survival. (For comparison, the smallest autosome, chromosome 22, has over 500 gene ...
