纯合的

Dihyborid An organism that is heterozygous at two loci, formed by crossing homozygous parents with different alleles at two given loci: for example, Mendel ' s cross between yellow round and green wrinkled garden peas to give a yellow round dihybrid.

双因子杂交：用两个基因位点上具有不同等位基因的纯合亲本杂交形成的杂合生物体。例如，在孟德尔的杂交试验中，黄圆和绿皱杂交生成杂合子黄圆。

It is proved that a left R-module P is pure projective if and only if for any pure epimorphism E→M→0, where E is pure injective, Hom→Hom→0 is exact.

证明了左R-模P是纯投射的当且仅当对任意纯满射E→M→0，其中E是纯内射的，Hom→Hom→0是正合的。

AIM: To investigate genome-wide loss of heterozygosity and homozygous deletion in human pancreatic cancer cell lines.

目的：研究胰腺癌细胞基因组范围内的纯合性缺失和杂合性缺失(loss of heterozygosity， LOH)。

Mouse models of this genetic defect have been unsatisfactory because homozygote null animals die early in development and heterozygotes do not exhibit a cardiac phenotype.

这种遗传缺陷的小鼠模型并不能令人满意，因为纯合子缺陷动物在发育早期就会死亡，而杂合子又不能显示心脏表型。

The effects of different light quality (blue light, red light and mixed blue and red light) on propagation of young stem and taking root in Hetao honeydew melon are shown. In regenerative whole plants, domestication was taken and suitable transplanting condition was studied.

对形成的植株进行了单倍体植株的鉴定，同时对获得的单倍体植株进行了染色体的加倍和鉴定，获得了纯合二倍体，通过对获得的纯合二倍体经过田间比较和鉴定，筛选出了部分优良的单株和株系。

The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.

结果表明，白来航鸡的白羽和寿光鸡的黑羽对藏鸡麻羽的遗传方式是完全显性遗传；麻羽是由两个或两个以上的等位基因决定的，只有同时存在这两个或两个以上的等位基因，才可能表现出麻羽来；决定胫色性状的Id/id基因为伴性遗传，隐性基因id在纯合子时有个逐步表达的过程；本研究证实了所用白来航公鸡胫色性状的基因型为显性纯合子。

Feather color and shank color performance and separated proportion of F1 and F2 were observed. The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.

The distribution of NAT2 polymorphisms was different between the recurred group and the control group. The polymorphism of NAT2 would increase the risk of recurrence in the population with history of rectal adenoma. However, there is no difference for NAT2 rapid and slow acetylator between two groups.

NAT2多态性在腺瘤复发组与对照组中的分布是有差异，NAT2非野生纯合型(Wt/M〓+M〓/M〓)为直肠腺瘤复发的危险因子，特别当在非野生纯合型中的NQO 1 C/T+T/T型及MTHFR C/T+T/T，其相对危险度分别可达：3.27(95％CI 1.01-10.65，P＝0.043)和3.28(95％CI1.00-10.84，P＝0.046)。

Deduced by the proportion of typical sterile plants and normal fertile plants in segregative generations derived from WA zhenqiuA/6078 that:I gene could inhibit the expression of Rf gene completely by the heterozygosity of 1 pair of Rf in genotype;and only reduce the expression of Rf genes with two heterozygous Rf genes in genotype ;but it would never inhibit the expression of Rf genes if the genotype included 3 pairs of heterozygous Rf genes. When Rf gene was homozygous,the / gene could not inhibit the expression of it.

根据认叭真秋刀6078各衍生分离世代中典型不育株和正常可育株所占比例推断：基因型中仅包含1对杂合的Rf基因时，I对Rf的表达起完全抑制作用；基因型中包含2对杂合的Rf基因时，I仅对Rf的表达起削弱作用；当基因型中包含3对杂合的对基因时，I对Rf的表达不起抑制作用；I对纯合位点的Rf的表达不起抑制作用。

Methods:The difference of PTH gene and protein expression in parathyroid gland and thymus were compared between PTH knock-out mice 1αase knock-out mice and their wild-type littermates at 2 weeks of ages by RT-PCR,real-time PCR and immunohistohemistry.

real-time PCR和免疫组织化学的方法比较分析同窝2周龄PTH基因敲除纯合子和野生型小鼠以及1-α羟化酶基因敲除纯合子[1αase-/-]和野生型小鼠的甲状旁腺和胸腺的PTH表达差异？

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。
