查询词典 Z chromosome

Based on the hereditary properties of NPV resistance, a hypothesis was proposed and confirmed that the resistance is controlled by NN main gene on an autosome and Z + Z + minor genes on the sex chromosome.

根据其遗传规律的特殊性，提出常染色体上NN主基因和性染色体上Z+Z+修饰基因控制假设，并得到试验验证。

Additionally, analysis of G-banding patterns for macrochromosomes of them indicated that there was great difference between NO.1 and NO.2 chromosome, which can be explained by the pericentric inversions.

NO.l染色体，家鸡为m型，而鹌鹑为sm型；NO.4、NO.6、NO.8和Z染色体，家鸡分别为sm、sm、m、m型，而鹌鹑全为t型。G带分析结果显示，家鸡和鹌鹑的G带差异主要反映在NO.1、NO.2染色体上，这可能是由於臂间倒位所致。

With the new herbicide-oryzalin to treat the callus with young buds of coloured Zantedeschia aethiopica in vitro, the effects of oryzalin of different concentration and time duration on doubling chromosome of coloured Z. aethiopica were studied.

用新型除草剂Oryzalin作为彩色马蹄莲体细胞染色体加倍的诱导剂，以愈伤组织芽点为处理材料，研究了不同处理浓度和处理时间的除草剂对彩色马蹄莲染色体加倍的影响。

The allele D of all four alleles which belong to locus LE0I0229 on Chromosome Z had positive effect on SS.

影响40周龄蛋壳强度的标记为Z染色体上的标记LEI0229，该标记有4个等位基因，其中只有等位基因C对蛋壳强度有影响，且为正效应。

The egg production of a week et al was also analyzed . 18 pairs of microsatellite primers were screened from chromosome 1 and chromosome Z, the primers were designed to allow optimal performance of the markers, in sets containing multiple microsatellites, on ABI3100 sequencers. We determined there were correlation among 13 microsatellite markers and 19 characters in 25 egg traits through least square means. At the same time, we calculated correlation among characters of egg traits in silkies.

从鸡1号染色体和Z染色体上筛选出18对微卫星标记，进行多重PCR扩增，并对引物组合的反应体系进行优化，在F1群体中检测到13个标记位点分别与25种性状中的19种性状有不同程度的相关，并进行同一标记不同基因型间的多重比较，同时还计算了产蛋性状间的表型相关。

Based on different DNA fragments between Z and W chromosome, the developed PCR method has no risk of the mistrial of those sex identification markers depended on W chromosome, and can omit extra internal control or restriction enzyme deigestion. The DNA-based spindlin gene approach can provide a rapid, exact and low cost method for sex identification in poultry.

本研究以PCR检测家禽Z与W性染色体中之纺缍体蛋白基因intron序列，以其长度的差异来鉴定家禽性别，可避免仅检测W染色体性别鉴定标记的误判，且不需再搭配内部对照，更不需结合限制酶切割法即进行家禽性别鉴定。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
