Abstract:

Summary Two lines of White Plymouth Rock chickens that have been divergently selected for 8‐week body weight for 31 generations were compared for patterns of DNA fingerprints (DFP). Digestion of DNA with HinfI and hybridization to Jeffreys' minisatellite probe 33.6 resulted in DFPs that were relatively similar within lines (bandsharing = 0.50) and less similar between lines (bandsharing = 0.22). Analyses of scorable DFP bands produced by mixing DNA from individuals within lines indicated that 48% were line‐specific. Causes for the differences in DFP patterns between lines and for occurrence of line‐specific bands for the two lines divergently selected for body weight are discussed. 1990 International Society for Animal Genetics
