| 1. | The identification and manipulation of genetic loci determining quantitative traits ( quantitative trait loci ( qtls ) ) is important in plant and animal breeding
在动植物繁育过程中，对人类具有重要的经济价值。 |
| 2. | The centromere is a specific genetic locus and remains relatively uncoiled during prophase , appearing as a primary constriction
着丝粒是一个特化的遗传区域，在细胞分裂的早期始终保持解开的结构，所以也叫做主缢痕。 |
| 3. | We carried out a genomewide association analysis to identify additional genetic loci associated with an increased risk of rheumatoid arthritis
我们采用染色体组关联分析确定附加遗传基因座与类风湿关节炎的风险增高有关。 |

| 5. | Flavonoid - 3 ' , 5 ' - hydroxylase ( f3 ' , 5 ' h ) corresponding to the genetic loci hfl and hf2 , a member of the cytochrome p450 family , is the key enzyme in the anthocyanin biosynthesis , which is generally required for blue or purple flowers
本研究以紫蓝色矮牵牛基因组dna为模板，利用pcr技术获得了两个扩增产物，分别将其克隆至pgem - teasyvector上，进行了全序列分析。 |
| 6. | About 158 ploymorphic genetic loci in 169 obtained genetic loci are amplified and the amplified dna fragments varied in size from approximately 3000bp to 150bp . the numberof bands are from 1 to 17 per primer . the range of genetic distances among eleven strains is from 0 . 3009 to 0 . 7333 . the dendrograms based on rapd and issr data clearly indicated that eleven strains artemia are divided into four species
用17种issr引物对卤虫基因组dna进行扩增，均扩增出清晰可辨的条带，共获得169个基因座位，其中有158个多态性基因座位，多态性基因座位比率为93 . 49 。 |
