奴态

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.

设计8对引物，应用聚合酶链式反应-单链构象多态性技术检测促性腺激素释放激素受体（gonadotropin releasing hormone receptor， GnRHR）基因外显子1、外显子2和外显子3在高繁殖力品种和低繁殖力品种（南非肉用美利奴、考力代和中国美利奴绵羊）中的单核苷酸多态性，同时研究该基因对小尾寒羊高繁殖力的影响。

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.

采用PCR-SSCP技术检测抑制素α(inhibin α，INHA)基因5'调控区、外显子1，骨形态发生蛋白4(bone morphogenetic protein 4，BMP4)基因外显子2、外显子3和外显子4以及骨形态发生蛋白7(bone morphogenetic protein 7，BMP7)基因外显子2和外显子3在高繁殖力绵羊品种以及低繁殖力绵羊品种(中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊)中的单核苷酸多态性，同时研究这三个基因对小尾寒羊高繁殖力的影响。

By its servility it is the prey of tyranny, and by its credulity it is the foe of enlightenment.

因为他的奴态成为了暴君的猎物，因为他的轻信顽固成为了启蒙的天敌。

Four sheep lines, HU-Yang, Chinese M erino monotocous, Chinese Merino multiparous for wool production and Chinese Merino multiparous for mutton production, were used in this study. Litter sizes were recorded for each ewe in the four lines. Primers for BMP15 and BMPR-IB gene were designed from database sheep sequence and polymorphisms were detected by PCR-RFLP method.

以绵羊BMP15基因和BMPR-IB基因为候选基因，以湖羊、中国美利奴单胎品系、中国美利奴肉用和毛用多胎品系为研究对象，采用PCR-RFLP方法对候选基因进行单核苷酸多态性位点检测和基因型分析，同时研究基因对绵羊产羔数的影响。

Genetic polymorphism and aggregation of seven sheep populations, including three breeding sheep populations (breeding F1, F2 and Bamei mutton sheep), three introduced mutton sheep breeds (Texel, Dorset and German Merino sheep) and one local female parent population, were assessed using 10 microsatellite markers.

方法］利用10个微卫星标记对3个选育绵羊群体（选育级进1代、级进2代、巴美肉羊），3个引进肉羊品种（德克塞尔、无角道塞特、德国美利奴）和1个当地母本群体进行微卫星标记鉴定，分析这7个绵羊群体的多态性和遗传聚集性。

Goodness; moral excellence; good quality 美德;德性;优点 Virtue carried to extremes can turn into vice; humility, for example, can degenerate into servility and spinelessness.

美德推到极点可能成为邪恶；例如，谦卑可能堕落为奴态和无骨气。

BMPR-IB gene as a fecundity candidate gene was studied in Cele sheep(44 blood samples), Duolang sheep(49 blood samples), Hu sheep (32 blood samples),Chinese Merino monotocous line(40 blood samples) and Chinese Merino (47 blood samples) by PCR-RFLP.

本研究以绵羊BMPR-IB基因作为多胎候选基因，采用聚合酶链式反应—限制性片段长度多态性技术，对策勒羊(44只)、多浪羊(49只)、湖羊(32只)、中国美利奴羊多胎类型(40只)以及中国美利奴羊(47只)进行了分析研究。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
