We have used backcross progeny from a cross between two inbred lines of chickens to construct a linkage map of the chicken. The map currently consists of 100 loci, identified using either anonymous cloned fragments of genomic DNA or sequences corresponding to cloned genes. Parent birds were derived from two lines of White Leghorn chickens, which differ in susceptibility to a number of diseases. Restriction fragment length variants were identified by comparison of the DNA of these two parent birds using a panel of seven restriction enzyme digests and the segregation pattern observed in progeny of these two birds. Restriction fragment length variants were detected for approximately 41% of the clones tested, whether these were known genes or random genomic fragments. This high level of variability was also reflected in the presence of variation within the parental lines for some clones. The overall size of the linkage groups and the progressively higher incidence of linkage as further clones were added suggests that the map covers the majority of the genome, although it is unlikely that there are marker loci on all the microchromosomes. The present map will be of use in locating genes affecting disease resistance, but also illustrates the relative ease with which such maps for the chicken can be constructed.
