Amongst the various available DNA markers, DNA fingerprints are the most documented in genetic studies of chickens (Dunnington et al., 1994 and Lamont et al., 1996). The utility of the DNA fingerprints (DFP) as genetic markers linked to quantitative trait loci (QTL) coding for economically important traits of chickens has been examined over various laboratories (Dunnington et al., 1992 ; Dolf et al., 1993 and Lamont et al., 1996). Most studies documented so far, are based on DFP probes: 33.6 (Jeffreys et al., 1985) and R18.1 (Haberfeld et al., 1991). Since majority of the loci detected in chicken genome by 33.6 are not linked to the loci detectable by R18.1 (Haberfeld et al., 1991), additional minisatellite loci could be surfaced by bringing in newer multi-locus probe (MLP)- restriction enzyme (RE) combinations, to explore greater number of QTLs segregating in different resource populations. Relying on these assumptions, a study was conducted to generate a DFP based marker system using above two probes in a variant genetic background and evaluate them as genetic markers linked to QTLs controlling few juvenile traits in meat type chickens.
