A set of spelt monosomic lines as female parent were respectively crossed with wheat new variety SM96 and new line SM20005 to determine the chromosomal location of the gene conferring resistance to powdery mildew in both. Seeding of parents, F〓 and F〓 from monosomic F〓 were inoculated with race no. 15 of Blumeria graminis f. sp. tritici. Analysis of obtained data revealed that one major dominant resistant gene originating from wild Emmer in the variety SM96 and the line SM20005 was located on chromosome 4A.

为确定小麦新品种沈免96和新品系沈免20005含有的抗白粉病基因所在染色体，以一套斯卑尔脱单体系为母本分别与沈免96和沈免20005杂交，将亲本、F〓、单体F〓植株的F〓代群体在苗期用小麦白粉菌15号小种的单孢菌系接种鉴定，单体分析结果表明，沈免96及沈免20005所含源于野生二粒小麦的抗小麦白粉菌15号小种的1个显性主效基因位于4A染色体上。

For example, neural tube defects （NTDs--anencephaly, spina bifida, encephalocele, myelomeningocele） usually have multifactorial causes, although they also have many specific known single-gene, chromosomal, and environmental causes.

例如神经管缺陷（NTD，包括无脑，脊柱裂，脑膨出，脊髓脊膜膨出）通常有多基因造成，虽然也有许多已知的单基因，染色体和环境原因。

例如神经管缺陷（NTD，包括无脑，脊柱裂，脑膨出，脊髓脊膜膨出）通常有多基因造成，虽然也有许多已知的单基因，染色体和环境原因。

The aim of study was to investigate the importance of chromosome aberration in differential diagnosis of eosinophilia and the chromosomal aberrations involved in patients with clonal eosinophilia. 65 cases of eosinophilia were collected and chromosome specimens of bone marrow cells were prepared by 24hour culture, and Gbanding technique was used for karyotyping.

为探讨染色体异常克隆在嗜酸性粒细胞增多症诊断和鉴别诊断中的意义及克隆性嗜酸性粒细胞增多症涉及的染色体异常，收集了65例嗜酸性粒细胞增多患者的骨髓标本，培养24小时，采用G显带进行核型分析。

Histone H3 methylated at Lys4, which defines euchromatin, was not only distributed across most of the chromosomal landscape but was also present at the centromere core, the site of kinetochore assembly.

标志着常染色质的组蛋白H3－K4甲基化不仅广泛分布在大部分的染色体区域，同时也存在于着丝点的中心位置。

The common features of imprinted genes are, clustering of multiple imprinted genes in one chromosomal region (around 80%), conservation of imprinting among eutherian mammals, asynchrony of DNA replication of imprinted genes, temporal and spatial regulation of expression of imprinted genes, coding for untranslated RNAs as well as proteins, antisense transcripts may regulate expression of imprinted genes. Once established, the imprinting pattern is stably transmitted through cell division but reset in germ cells of the fetal gonads.

约80%的印记基因呈串出现在染色体上；在哺乳动物品种之间，印记基因具有较高的保守性；印记基因的复制通常表现为不同时性；一些印记基因具有印记遗传的时空性；少数印记基因只转录为mRNA而不翻译成蛋白质；印记基因的反意链通常表达，表达产生具有调节印记基因的作用。
