The number of the chromosomes in Henan large tail sheep is 2n=54, the karyotypes of male and female sheep are 54, XY and 54, XX, respectively. There are 26 pairs of autosomes and 1 pair of sex-chromosome. Among 26 pairs of autosomes, 3 pairs are metacentric chromosomes, 23 pairs are telocentric chromosomes. X chromosome is the biggest subtelocentric chromosome and Y chromosome is the smallest submetacentric chromosome.

Abnormal chromosome was detected in 17 fetuses. Among them, trisome 21, trisome 18, trisome 13, Turner syndrome, Klinefelter syndrome, short arm deletion of chromosome 18, and inverted chromosome 9 were detected in 8, 3, 1, 1, 1, and 2 fetuses, respectively. Abnormal chromosome was found in 5 out of 8 fetuses who received serum screening. Ultrasound showed abnormal chromosome in 11 fetuses.

The single micronucleus and multi-micronucleus were observed at the interphase. The chromosome aberrational cells including chromosome fragment, lagging chromosome, chromosome bridge and circular chromosome were found during the mitosis. RAPD analysis of seedling genomic DNA variation in M 2 generation of three mutants showed their DNA sequences had changed. The result confirmed that the implantation of 7Li +3 ions could induce genetic mutation in wheat.
对幼苗根尖细胞学研究观察,获得单桥、双桥、桥断裂、落后染色体、三级、断片和微核等畸变类型;对已获得的小麦突变株,分别进行M2 代DNA分子的RAPD分析,结果发现DNA均发生变异,证明7Li+ 3 注入通过内靶核反应能够诱发小麦在分子水平上产生遗传变异。

CML is cytogenetically marked by the philadelphia chromosome, which originates from a reciprocal translocation between chromosome 9 and 22 and is molecularly marked a chimeric bcr-abl gene, resulting from juxta-positive of the abl proto-oncogene on chromosome 9 with the bcr gene, which is normally located on chromosome 22. The chimeric bcr-abl gene expression an 8. 5kb hybrid mRNA transcript giving rise to a 210-KD fusion protein (P210〓) with increased tyrosine kinase activity. P210〓 plays a key role in the pathogenesis of CML. The continuous cell line K562 was established from the pleural effusion of a 53-year-old female with CML in terminal blast crisis, and was a human erythroleukemia line, contained Ph chromosome.
绝大多数慢粒患者白血病细胞中具有Ph染色体,是由9号染色体长臂3区4带和22号染色体长臂1区1带相互易位形成,即t(9;22),使位于9q〓的c-abl原癌基因在第二外显子的5'端断裂并易位到22 q〓的M-bcr基因第2或第3外显子的3'端,形成异常的bcr-abl嵌合基因,该基因转导出异常的mRNA,编码并翻译出P210蛋白,该蛋白具有很强的酪氨酸激酶活性,使粒细胞发生恶性增殖。K562细胞属于慢粒急变、红白血病细胞株,具有Ph染色体。

As for digenic interaction, 18 pairs of epistatic loci with R2≥5% were resolved with a mean R2 of 6.9%, ranging from 5.1% to 11.8%, which was slightly larger than that of the main-effect QTLs identified for the traits. The majority of the main-effect and epistatic loci detected for seedling vigor related traits were clustered in a few chromosome regions.
种子活力相关性状的大多数主效应和互作QTLs成串分布于少数几个染色体区段(chromosome regions, CRs),并且成串分布在同一染色体区段的QTLs效应的方向总是一致,该结果与这些性状在表型上的正相关相一致。

The results showed that karyotypic type of Ya01-21was 2n=104=100m+4sm(4SAT), Chromosome length ratio of the longest and the shortest 4.25, the average arm-ratio 1.35, belonging to 2C type of chromosome. Molecule identified combine with chromosome studied indicated that Ya01-21 was a progenies of Erianthus arundinaceum. following the law of n+n; ITS identify showed that Ya01-21 is a progenies of Erianthus arundinaceum, the somatic chromosome karyotypic type of Ya01-36 was 2n=132=130m+2sm, Chromosome length ratio of the longest and the shortest 3.94, the average arm-ratio 1.27, belonging to 2B type of chromosome, combining the advance of characters the law of 2n+n can be resumed.
研究结果表明,崖城01-21的体细胞染色体核型公式为2n=104=100m+4sm(4SAT),最长与最短染色体的长度比为4.25,平均臂比1.35,染色体属2C型,分子鉴定结合细胞学研究认为其为斑茅的真实后代,其染色体遗传为n+n;崖城01-36经ITS签定为真实杂种,其体细胞染色体核型公式为2n=132=130m+2sm,最长与最短染色体的长度比为3.94,平均臂比1.27,染色体属2B型,结合其性状的进展,推断亲本向其传递染色体可能以2n+n的方式进行。
