Before revision: The "genome " of any given individual is unique; mapping the "human genome " involved sequencing samples collected from a small number of individuals and then assembling the sequenced fragments to get a complete sequence for each of the 23 human chromosome pairs (22 pairs of autosomes and a pair of sex chromosomes, known as allosomes).
