纯合的

The muta2 tion gene of shedding hair is a single recessive gene on autosome , and the genetype were AABBccDD、AaBbccDD in inbred strain and closed colony.

确定突变基因的类型为纯合单一隐性遗传，近交系毛色基因可能为AABBccDD ，封闭群的毛色基因可能为AaBbccDD。

Thus most mutations show in the phenotype only when they are homozygous.

表型的变化只有在纯合状态才能表现出来。

No homozygous deletions were found in the MTS1 gene,while point mutations were found in 2 of 18 bladder cancers.

研究表明在多种肿瘤细胞中存在着MTS1基因的纯合缺失和点突变［3～7］。

Objective To study the relationship between homozygous deletions of p16 gene and calcitonin hypermethylation and chronic myeloid leukemia blast crisis.

目的 探讨p16基因纯合缺失、降钙素基因高度甲基化与慢性粒细胞白血病急变之间的关系。

From cauliflower accessions, we isolated four true lines of different curd types: smooth curd curd-s, haired curd curd-h, crystal curd curd-c and thorned curd curd-t.

本项研究从花椰菜变种中分离出4种花球类型的纯合株系。光滑型花球curd-s；、毛状物花球curd-h、颗粒状花球curd-c和刺状物花球curd-t。

Tetraploid induction from double haploid was also studied, and a desirable result has been obtained. Dripping the apical point of plantlets with 0.2% colchicine plus 1.5% DMSO was a suitable treatment with doubling frequency 18.2%.

其中0.2％秋水仙素+1.5％DMSO滴苗处理，效果较明显，加倍频率达18.2％。1％秋水仙素+羊毛脂膏+1.5％DMSO涂抹生长点试验，加倍率为14.0％，由于此法田间工作量小，不失为双单倍体诱导纯合四倍体较好的方法。

In conclusion, the number of born alive per litter was not affected by the half-sib mating method after two generations of selection in the homozygotic GPI/PGD line of Lanyu pigs.

结果显示兰屿猪种GPI/PGD遗传型纯合品系采半同胞配种和两个世代选拔后，进亲配种并未影响到母猪的产仔数。

Three full-sibling binary CMS lines, 11 back-cross binary CMS lines, 10 half-sibling binary CMS lines, 10 isozygoty CMS lines and five restorer lines were chosen to make 50 single hybrids and 120 modified single cross hybrids by the way of NC Ⅱ design. The plots of F1 were arranged in the field in a randomized complete block design with 2 replications and the combining ability of 7 characters were analyzed using random model.

利用3个全同胞型二元不育系、11个回交型二元不育系和10个半同胞型二元不育系及其10个亲本纯合不育系，分别与南恢04、明恢86、辐恢838、先恢207和密阳46等5个恢复系按照NCⅡ交配设计配制了50个单交种和120个改良单交种，按随机区组的随机模型分析方法，对二元不育系主要性状进行了配合力分析。

Their frequencies of GUS expression in pollens were 97.755% 0.800% and 96.556% 0.600% respectively.

利用GUS基因在T1花粉中的表达鉴定获得转基因纯合植株。

If wild-type males are crossed into hermaphrodites that are homozygous for all three mutations.

如果野生雄性与雌雄同体杂交，会产生这三种突变的纯合子。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
