Model of genetic control of the number and location of nipples in domestic pig

Model of genetic control of the number and location of nipples in domestic pig In domestic pig, the number and location of nipples is considered a single quantitative trait, which has a complex spatial structure that includes bilaterality and a linear sequence of repetitive elements. According to this hypothesis, six inadherent biallelic loci are sufficient for a variety of traits observed in domestic pig populations. Verification of representative samplings from five domestic pig populations of different origin (about 20 000 individuals) confirmed the theses of the hypothesis, which allows considering it as a model of the studied bilateral trait. Using the model, the intraclass pheno- and genotypic diversity was examined and the relationship of the trait manifestation asymmetry with heterozygosity of loci that control it was shown. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

In domestic pig, the number and location of nipples is considered a single quantitative trait, which has a complex spatial structure that includes bilaterality and a linear sequence of repetitive elements. According to this hypothesis, six inadherent biallelic loci are sufficient for a variety of traits observed in domestic pig populations. Verification of representative samplings from five domestic pig populations of different origin (about 20 000 individuals) confirmed the theses of the hypothesis, which allows considering it as a model of the studied bilateral trait. Using the model, the intraclass pheno- and genotypic diversity was examined and the relationship of the trait manifestation asymmetry with heterozygosity of loci that control it was shown.
