Chromosome 11 (human)
Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs (the building material of DNA) and represents between 4 and 4.5 percent of the total DNA in cells.
At 21.5 genes per megabase, Chromosome 11 is one of the most gene-rich, and disease-rich, chromosomes in the human genome.
More than 40% of the 856 olfactory receptor genes in the human genome are located in 28 single-gene, and multi-gene, clusters along this chromosome.

# Genes
The following are some of the gene count estimates of human chromosome 11. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). Among various projects, the collaborative consensus coding sequence project (CCDS) takes an extremely conservative strategy. So CCDS's gene number prediction represents a lower bound on the total number of human protein-coding genes.
