All of the four milk protein loci exhibited polymorphism with allele frequencies of 0.862 +/- 0.017 for alpha(s1)-casein B, 0.966 +/- 0.0009 for beta-casein A, 0.712 +/- 0.0224 for kappa-casein A and 0.567 +/- 0.0245 for beta-lactoglobulin B. The mean heterozygosity estimated over all the four milk protein loci was 0.3015. Genetic equilibrium was observed among all of the loci investigated, except kappa-casein. Chi-squared tests revealed that there was no significant linkage among studied milk protein phenotypes.eninfo:eu-repo/semantics/closedAccessFood science & technologyMilk proteinHolstein cattleGenetic polymorphismBos taurusLociAssociationVariantsCaseinCows milkProduction traitsDairy-cattleBeta-lactoglobulinArticle0002391183000042-s2.0-33746116914180182593Food science & technologyCaseins; Cheesemaking; Milk CurdsUnclassified drugMilk proteinKappa caseinCaseinBeta lactoglobulinBeta caseinAlpha caseinProtein polymorphismPriority journalPhenotypeNonhumanHeterozygosityGenetic variabilityGenetic linkageGene frequencyGel electrophoresisChi square testCattleArticle
