abstract
Restriction fragment length polymorphisms (RFLPs) were observed in BamHI-digested mouse DNA probed with a cDNA for human fibronectin. Analysis of the inheritance of fibronectin RFLPs in AKXD and SWXJ recombinant inbred strains of mice mapped the locus, Fn-1, to the midregion of mouse chromosome 1 about 4 cM distal from the loci encoding gamma-crystallins (Cryg). Loci homologous to genes in the centromeric third of mouse chromosome 1 are also syntenic in rats, humans, and cattle and may, therefore, mark a large conserved chromosomal segment of the mammalian genome.
