At last in this paper, the sequences of CHD-W gene in Chinese Egret, Cattle Egret and Black-faced Spoonbill,and the sequences of CHD-Z gene in Chinese Egret, Large Egret, Intermediate Egret, Cattle Egret, Night Heron and Black-faced Spoodbill were analyzed and used to study their relative and phylogenetic evolution .

本文最后对黄嘴白鹭、牛背鹭和黑脸琵鹭的W染色体上扩增的CHD片段，以及黄嘴白鹭、大白鹭、中白鹭、牛背鹭、夜鹭和黑脸琵鹭Z染色体上扩增的CHD片段进行序列分析并用于亲缘关系及系统进化的研究。

Aneuploidy The condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number.

非整倍性：在减数分裂的过程中同源染色体不分离而造成的一条或多条染色体的缺失或增加。

There is a significant increase with age in the number of micronuclei and missegregation. Nondisjunction of chromosome 21 is much more frequent than loss in vivo and in vitro. No significant difference in nondisjunction between male and female was noted.

在不同年龄正常人外周血淋巴细胞中，微核数随年龄的增加而增加。21号染色体不分离与年龄的关系极显著，无论在体内还是体外，21号染色体不分离远远高于丢失。

Aneuploidy is that cells or individuals possess abnormal chromosome number resulted by nondisjunction during cell division .

非整倍体指染色体分离异常所导致的染色体数目非整倍性改变所得到的细胞与个体。

Methods Lymphocytes were obtained from healthy donors of different ages, both sexes, and were treated with cytochalasin B. Binucleated cells were hybridized with chromosome 21 specific probe, and simultaneously, chromosome 21 loss and nondisjunction were detected.

用细胞松弛素B处理不同年龄及性别正常人外周血淋巴细胞获得的双核细胞，以21号染色体近着丝粒特异性探针进行荧光原位杂交，同时检测21号染色体丢失及不分离。

Chromosomes 6 and 7 were both nucleolus organizing chromosomes.

第6和第7染色体两者是组成核仁的染色体。

The analysis result indicates that the chromosome number of 38 accessions is ranged from 63 to 90 as same as septuploid, octoploid, enneaploid and decaploid, respective.

结果发现台湾鱼腥草收集品染色体数目介於63~90条之间，分别为七、八、九及十倍体，另发现染色体数84与85条之异数体收集品。

It was named DDx24.The sequence of 0876g05 is 100% homologous to one segment sequence of humanchromosome X.Both genes have been registered in GenBank.

可以确定此基因为人类新基因，并经国际基因命名委员会命名为人DDx24基因；基因0876g05核苷酸序列与人类X染色体上一段序列100%同源，未发现同源性大于80%的已知人类基因，同样确定此基因为人类新基因，将该基因定位于人类X染色体Xq2

Results: Osteopetrosis is a group of rare, heritable disorders of the skeleton characterized by increased bone density with typical X-ray manifestation. It can be divided into autosomal recessive osteopetrosis and autosomal dominant osteopetrosis. The prognosis vary greatly in different clinical type.

结果：石骨症是罕见的家族性先天性骨疾病，以骨密度增高为主要表现，分常染色体显性遗传和常染色体隐性遗传，分型不同，临床表现不同，X线有特征性改变，治疗上以对症治疗为主，造血干细胞移植被用于治疗本病。

Results Chromosomal imbalances were demonstrated in 6 cases. Overrepresentation of genetic material was detected in 4 cases on Chromosome 2p and 10q, and 3 cases on Chromosome l8q.

结果 10例中枢神经细胞瘤中，6例发现有染色体的失衡，主要表现为遗传物质在染色体2p(4、10)、10q(4/10)和18q(3/10)上的获得。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
