| Abstract: | Special methods allowing usage of inadequate pedigrees were employed to examine linkage among the milk protein loci alpha s1-casein, beta-casein, chi-casein and beta-lactoglobulin, and the loci for serum amylase, ceruloplasmin and transferrin. Linkage was evident between the alpha s1-casein and beta-casein loci, the alpha s1 and chi-casein loci, the beta-casein and chi-casein loci, also amylase and transferrin loci. Recombination fractions for these corresponding combinations were 0.00; 0.00; 0.00 and 0.30. Weak linkage (recombination fraction being 0.46; 0.44 and 0.42) between the beta-lactoglobulin and beta-casein loci, the amylase and ceruloplasmin loci, ceruloplasmin and transferrin loci is supposed. |
