基因替代模型的分析表明，αs1-CN位点B基因对C的替代显著影响305天产奶量，对乳脂率无显著影响，β-CN A1基因的替代对305天产奶量乳脂率和乳蛋率均有显著影响作用，κ-CN和β-LG位点A基因的替代对生产性能均无显著效应。

There were three isozyme (AMY1, AMY2 and AMY3) at the locus of amylase in Qinghai Merino, moreover, there were two genotypes of AMY2A and AMY2O at the AMY2. Monomorphism was tested at the locus of AMY in Gansu Alpine Merino. The degree of genetic variability estimated by Nei's expected average heterozygosity for the 6 blood protein loci was relatively higher in Gansu Alpine Merino and in Qinghai Merino than that in others, which indicated that there are higher genetic variations and richer genetic diversity in Alpine Merino.

从6个血液蛋白位点的Nei氏预期平均基因杂合度所估计的群体内的遗传变异以及与本研究其它群体的结果相比来看，甘肃高山细毛羊和青海细毛羊的群体内的遗传变异相对较大，而其它群体内的遗传变异则相对较小，说明高原型细毛羊群体内遗传变异程度较大，遗传多样性较丰富，具有较大的选择潜力，为高原型细毛羊进一步选育提高提供了遗传基础。

Single locus probe PMLJ14 recognizes the locus of D14S13 in human genome. Hae Ⅲ digested band-frequency was drawn from 269 unrelative individuals. The probability of personal identification is 97～99. 98% and parentage testing is 91.4～98.6%.
