Evidence for a strong inherited component in RA is supported by a lot of data, and about 35% of genetic contribution to RA can be attributed to human leukocyte antigen class Ⅱcomplex.

许多研究表明遗传因素是导致RA发病的最主要原因，而在遗传因素中约35%来自于人类白细胞抗原Ⅱ类复合体。

The results of AMOVA indicated that the variance component of among populations contributes 51.53% to the total genetic variance.

基于Nei (1972)遗传距离的UPGMA聚类分析显示群体间的遗传距离与群体的地理距离关系一致。

To study the efficacity of space-induced towards the Artemia sinica spawn and select individuals with big genetic differences to propagate,this paper collect totally 59 space-induced and control Artemia sinic to carry out the genetic diversity inspection and relative's analyses using four sets of AFLP selective primers for amplification.

每对引物均获得清晰的扩增图谱，共检出222个清晰可辨的不同扩增片段，其中多态位点189个，占85.1%；UPGMA和NJ聚类分析图显示，来自空间诱变组的M5单独聚类，而其它58个个体聚为另一类，其他太空诱变组与地面对照组的个体交叉聚类，地面对照和太空诱变组遗传差异不明显。

Total 122 entophytic bacterial strains were categorized preliminarily to 35 groups based on colony morphology. 16S rDNAs were amplified with universal primers of bacteria, all the strains could produce a single band about 1500bp. The PCR products were digested with restriction endoenzyme HaeⅢand Msp Ⅰrespectively, and the different patterns were obtained for each enzyme, by combining all the restriction patterns for the two enzymes, the 122 strains could be grouped into 39 16S rDNA genotypes. The results indicated that endophytic bacteria from oilseed rape were genetically diversity.

分离获得的122株内生细菌，根据菌落形态可以划分为35类；利用细菌通用引物对16S核糖体DNA进行扩增，获得约1.5 kb片段，分别用内切酶HaeⅢ和MspⅠ对扩增产物进行限制性酶切，产生不同的酶切图谱；根据酶切图谱聚类分析结果，所有供试菌株被归为39类，这一结果从遗传上显示油菜内生细菌类群的多样性。

The relationship between the genetic distance and heterosis in corn was also discussed.

结果表明：(1)聚类结果与材料的亲缘关系和地理来源没有必然的内在联系，遗传距离不能代表亲本间遗传差异的大小，它可能反映的是材料间的形态差异。

From the RAPD analysis data, the band similarity rates and average band similarity rates between two individuals in the sampling population, average band allele frequencies, average band heterozygosis degree, and the Shannon genetic diversity index were calculated to perform the cluster analysis of heterozygosis arithmetic averages and construct the phylogenetic tree.

根据RAPD结果分别计算了两两个体间的带纹相似率、平均带纹相似率、带纹的平均等位基因频率和平均带纹杂合度及遗传多样性指数，作亲缘关系的类平均聚类并绘制了相关关系聚类图。

According to UPGMA cluster analysis, JCS diverged from DDC and DDS and formed another branch. This result confirmed that the similarity of genetic structure of DDC and DDS were more higher.

用 UPGMA 方法聚类， DDC 、 DDS 两组明显聚在一起，与 JCS 的遗传距离分别是0.2182、0.2744，进一步验证了三个组别遗传结构间的关系。

With the developing of statistical ideas in genetics and the spreading of computer, major gene and polygene mixed inheritance of quantitative trait is studied and applied extensively, and it has been researched seven kinds of mixed inheritance model by now.

随着现代统计学思想在遗传学领域的渗透以及计算机的普及和发展，数量性状的主基因-多基因混合遗传模型得到了广泛的研究和应用，现已完整的研究了7类混合遗传模型。

The results showed that the Shannon-weaver index of genetic diversity ranged from 1.3647 to 2.9964 and the Simpson index from 0.6111 to 0.9326, which indicated that the Cerasus has abundant genetic diversity.

同时在两大类内又将品种进行细分，第Ⅰ类分为3组，第Ⅱ类分为2组，其结果与地理分布有一定的相关性，能够反映樱桃的遗传特点及区域特性。
