chromosomes in humans can be divided into two types: autosomes (body chromosome(s)) and allosome (sex chromosome(s)). certain genetic traits are linked to a person's sex and are passed on through the sex chromosomes. the autosomes contain the rest of the genetic hereditary information. all act in the same way during cell division. human cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell. in addition to these, human cells have many hundreds of copies of the mitochondrial genome. sequencing of the human genome has provided a great deal of information about each of the chromosomes. below is a table compiling statistics for the chromosomes, based on the sanger institute's human genome information in the vertebrate genome annotation (vega) database. number of genes is an estimate, as it is in part based on gene predictions. total chromosome length is an estimate as well, based on the estimated size of unsequenced heterochromatin regions.
