Chromosome 2

Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs[4] and representing almost eight percent of the total DNA in human cells.

[7][8][9] The evidence for this includes: We conclude that the locus cloned in cosmids c8.1 and c29B is the relic of an ancient telomere-telomere fusion and marks the point at which two ancestral ape chromosomes fused to give rise to human chromosome 2.The following are some of the gene count estimates of human chromosome 2.

Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome vary.

So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes.

Fusion of ancestral chromosomes left distinctive remnants of telomeres, and a vestigial centromere
