The contig map provides more detail and depicts the order of overlapping DNA fragments. The new maps for chromosomes Y and 21 described in the accompanying article are contig maps that contain overlapping clones spanning entire chromosomal regions. Complete physical maps spanning the entire genome will facilitate the correlation of genetic and cytogenetic maps with the underlying DNA, offer access to clones from any region of interest, and provide material for large-scale sequencing. By correlating the inheritance of DNA markers with the appearance of biological traits in large numbers of related people, scientists can identify the chromosome on which a gene resides. Such markers include the DNA microsatellite repeats described in the accompanying article.
