The human genome is a complete set of DNA sequences for each of the 22 autosomes and the two distinct sex chromosomes. A small DNA molecule is found within individual mitochondria. These are usually t
TSC SNP distribution along the long arm of chromosome 22 (from https://web.archive.org/web/20130903043223/http://snp.cshl.org/ ). Each column represents a 1 Mb interval; the approximate cytogenetic position is given on the x-axis. Clear peaks and troughs of SNP density can be seen, possibly reflecting different rates of mutation, recombination and selection.
