绵羊KAP1.1基因多态性与毛纤维直径的相关性分析
Association of Polymorphisms of KAP1.1 Gene with Wool Fiber Diameter in Sheep
摘要
Abstract
This study used 768 Chinese Merino ( Xinjiang JunKen Type). Sequencing and PCR technology were used to analysis KAP1. 1( B2A) gene polymorphisms and association of KAP1. 1 gene with wool fiber diameter. The results showed six genotypes and 30 bp insertion/deletion of KAP1. 1 gene were existed in Chinese Merino( Xinjiang Junken Type) , which were A A genotype (341 bp) ,BB genotype (311 bp) , CC genotype (281 bp ) , AB genotype (341 bp/311 bp),AC genotype(341 bp/281 bp) and BC genotype(311 bp/281 bp) , respectively. Least square linear model( LSM) analysis indicated that the genotypes AA, BC , AC , AB and CC were not associated with wool curvature, Fineness Dispersion coefficient, staple length, fleece weight, clean fleece weight, wool density ( P ＞ 0.05). Genotype BB showed significantly less than BC,AA,AC,AB and CC genotypes in wool fiber diameter(P ＜ 0. 05 ) . KAP1.1I gene was proved to be closely related to wool fiber diameter, which can be used as a candidate molecular marker for wool fiber diameter in sheep.关键词
