title: A physical map of human chromosome 10 and a comparison with an existing genetic map.
abstract: A physical map for 13 loci on chromosome 10 was developed by determining the dosage of the corresponding DNA sequences in cell lines with unbalanced chromosome 10 rearrangements. Nine of the sequences were assigned to a smaller segment of the chromosome than previously and four sublocalizations were confirmed. The physical map covers most of chromosome 10, from 10p13 to 10q23. The linear order of loci within the physical map agrees with existing linkage maps of chromosome 10. A comparison between the physical map and existing genetic maps indicate an uneven distribution of recombination for chromosome 10. There appear to be hot spots of recombination in the regions defined by q21.1 and q22-q23. In addition, there is a suppression of recombination in the pericentromeric region in males which is not evident in females.
