trait correlation
1.Results AAP and LAP activity in serum were significantly higher for hepatobiliary disease subjects. Values increasing by degrees in order were acute disease of biliary trait . primary carcinoma of liver,a-cute icteric hepatitis, cirrhosis of liver,metastasis hepatocarcinoma and chromcity hepatitis B.It showed highly significant correlation between AAP and LAP in serum,correlation coefficient was 0. 976 2,.
2.The results showed that three genes such as HbB at Hb locus, TfC at Tf locus, Es- at Es locus diplayed certain correlation to the prolific trait of Small-tail Han sheep. Possibility of Ep to be used as the genetic marker should depend on further researches. The other four protein of AIb, Pr, AMY, LDH had no correlation to the prolific trait of Small-tail Han sheep, and couldn?t be used as the genetic marker.
3.This population was Genotyped for 1 1 microsatellite markers on ovine chromosome 1 .According to record of 5 traits, drew weight cumulative growth curve, relative growth curve and absolute growth curve and analyses phenotypic correlation among 5 traits and screened quantitative trait loci (QTL) for 5 traits.
4.The heart girth is the important correlation trait of weight of male and it ought to be regarded when indirect selection method for weight is applied as well as the cheast width,the body length,the height at withers and the circumference of cannon bone should be regard.
