查询词典 chromosome 12

Meiotic pachytene bivalents were obtained from porcine testes using prolonged hypotonic treatment combined with high chloroform Carnory's fixative solution. Mitotic metaphase chromosomes were prepared from blood cell culture. Comparative studies on division index and length of pachytene bivalents and mitosis metaphase chromosomes showed that those of the former are 5 times higher and 3.42(1.87～5.98) times longer than the latter, respectively. Chromomere maps of bivalents are more abundant than mitotic metaphase G-bands, while they are correspondent with mitotic early-metaphase G-bands. The result was found by using the chromosome 12 as a sample.

以性成熟公猪睾丸和外周血为材料，采用长低渗、高氯仿卡诺固定液固定和外周血细胞培养制备减数分裂粗线期二价体和有丝分裂中期染色体，通过对二价体和有丝分裂中期染色体分裂指数和长度的比较研究，发现二价体的分裂指数和长度分别是有丝分裂中期染色体的5倍和3.42倍(1.87～5.98)；同时以12号染色体为例，比较了二价体上的染色粒结构带与有丝分裂中期染色体G-带，表明染色粒结构带比中期染色体G-带带纹丰富，而与早中期G-带带纹吻合。

Two QTL for NSC translocation rate were identified on chromosome 12 and accounted for 8% and 14%, respectively, of the total variation.

These genes appear most frequently on chromosome 12 but rarely on chromosome 21 and Y.

The data byχ~2 were consistent with the separation ratio as 1: 2: 1 χ~2=4.028＜χ_(0.05,2~2=5.99, which further conformed that glandless character was controlled by a incomplete dominance gene, Gl_2~e. 2. SSR markers every about 5cM were selected in the chromosome 12 of our lab genetic linkage map to screen the parent plants. The markers with the polymorphism were used to amplify the DNA of 210 F_2 segregating plants selected randomly and recorded the marker genotypes. After eliminating the segregation distortion markers byχ~2 test, other SSR markers were detected by linkage analysis.

二、参照本实验室海陆种间遗传连锁图谱第12染色体上的SSR标记，平均每5cM左右选择一个标记进行亲本多态性的筛选，筛选出具有多态性的标记位点进一步扩增随机抽取的210个F_2群体单株的DNA，鉴定每个个体的标记基因型。X~2检测剔除偏分离标记后进行连锁分析，发现Gl_2~e基因位于CIR362与NAU5079之间，进一步参考图谱上位于CIR362与NAU5079之间的标记加密图谱，最终将其定位在CIR362和NAU2251b、NAU3860b、STV033之间。

When the researchers performed a detailed genetic comparison of affected and disease-free family members, they found that a specific segment of chromosome 12 was the most likely genomic hiding place for this unknown factor.

当研究人员对受影响的和未受影响的家族成员进行详细的遗传对比时，发现染色体12的一个特殊区段最可能是该未知因素的基因组藏匿部位。

RDNA was assigned to the telomeric region of Chromosome 15 and Chromosome 19 in dwarf-surf clam , and the same sequence was assigned on the proximal region of long arm of Chromosome 10 and on the telomere of short arm of Chromosome 12 in the hard clam .

18S-28S rDNA在两种蛤中有两个位点。rDNA探针定位在侏儒蛤的第15对和第19对染色体的端粒区域，同一序列定位在硬壳蛤的第10对染色体的长臂和第12对染色体短臂的端粒区域。

Classical genetic analysis suggested that Gl_2 was located in the chromosome 12, therefore Gl_2~e as its multiple alleles also located in the Chr 12 in cotton.

经典遗传学研究表明，Gl_2位于棉花第12染色体，因此作为它的复等位基因Gl_2~e也应位于棉花第12号染色体。
