Human gene map
The locations of the human genes. The location of each gene is called a locus (plural: loci). The total number of known gene loci on the human gene map as of June 24, 2000 was 6270. Chromosome 1 contained the most gene loci, namely 627, while the Y chromosome had the fewest, namely 24. The total distribution of the 6270 gene loci was as follows: {{}}chromosome 1 : 627 chromosome 2 : 379 chromosome 3 : 323 chromosome 4 : 247 chromosome 5 : 266 chromosome 6 : 380 chromosome 7 : 293 chromosome 8 : 210 chromosome 9 : 244 chromosome 10 : 218 chromosome 11 : 401 chromosome 12 : 336 chromosome 13 : 101 chromosome 14 : 194 chromosome 15 : 163 chromosome 16 : 241 chromosome 17 : 384 chromosome 18 : 89 chromosome 19 : 404 chromosome 20 : 136 chromosome 21 : 91 chromosome 22 : 142 chromosome X : 377 chromosome Y : 24
