查询词典 Merino

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。

The inhibin a gene、 the bone morphogenetic protein 4 (BMP4) gene and the bone morphogenetic protein 7 (BMP7) gene were studied as candidate genes on the prolificacy of Small Tail Han sheep. Single nucleotide polymorphisms of 5 ' regulatory region、 exon 1 of INHA gene;exon 2、 exon 3 and exon 4 of BMP4 gene and exon 2、 exon 3 of BMP7 were detected in high fecundity breed and low fecundity breeds (Chinese Merino sheep, Corriedale sheep and South African Mutton Merino sheep) by PCR-SSCP. The results indicated that there was a mutation (316C→T) in 5' region of INHA gene in Small Tail Han sheep, Chinese Merino sheep and Corriedale sheep, the same mutation did not exist in South African Mutton Merino sheep.

There were two genotypesin China Merino fecundity sheep,the BB and B+ mutation genotype was superior in Chinese merino fecundity sheep,the ewes with genotype BB and B+had 4.0 and 3.5 ovulations,genotype ++ had 1.56 ovulations averagely,The BB and B+ mutation genotypes were 2.44(P.01)and 1.94(P.01)ovulations more than with genotype ++ in the Chinese merino sheep.

绵羊的多胎是绵羊业多产、高产的基础。一般来说，家畜的繁殖性状是受多基因控制的数量性状，传统的选择方法对其遗传进展的改良是很慢的，世代间隔长。分子标记辅助选择为解决这一问题提供了新的方向和契机。

The gonadotropin releasing hormone receptor gene was studied as a candidate gene for the prolificacy of Small Tail Han sheep. Eight pairs of primers were designed to detect single nucleotide polymorphisms of exon 1, exon 2 and exon 3 of GnRHR gene in both high fecundity breeds and low fecundity breeds (South African Mutton Merino, Corriedale and Chinese Merino sheep) by PCR-SSCP. Only the products amplified by primers P4 and P7 displayed polymorphisms.

Polymorphism was detected for exon 3 of BMP4 gene in four sheep breeds. For exon 3, three genotypes were detected in four sheep breeds. In Small Tail Han, Chinese Merino, Corriedale and South African Mutton Merino sheep, frequency of genotype AA was 0.017, 0.216, 0.115, 0.429, frequency of genotype AB was 0.102, 0.317, 0.269, 0.500, frequency of genotype BB was 0.881, 0.467, 0.616, 0.071, respectively. Sequencing revealed one singlenucleotide mutation C→A at 305 bp of exon 3 of BMP4 gene in genotype BB in comparison to genotype AA, and this mutation resulted in an amino acid change of alanine→aspartic acid.
