- Humans have 22 chromosome pairs plus two sex chromosomes. 除了兩個性染色體之外，人體有22對染色體。
- Unlike other sex chromosome aneuploidy, there are no characteristic physical features for triple X patients. 由於大部分患者缺乏明顯的表現型特徵,造成本綜合征有相當大的鑒別難度。
- If neither of these explanations is true, though, it may mean that a secondary and more lethal mutation has emerged recently, and is now spreading in its turn. 如果上述解釋都行不通的話，那就意味著最近出現了二級病毒或者適應性更強的變異，而且已經開始擴散。
- All the new genes might be located at euchromosomes but MMSA-1 at sex chromosome. 除MMSA-1可能定位於性染色體，其餘均可能定位於常染色體；
- Besides,we discussed the sex chromosome and the mechanism of sex determination of Elaphodus cephalophus. 根據現存的幾種核型的分析對毛冠鹿的性染色體及性別決定機製作了初步的探討。
- Mammals normally have two sex chromosomes. 哺乳動物正常情況下有兩種性染色體。
- Method: Studying of normal and sex chromosome by classic cytogenetic analyse in leukemia patients before and after treated by allo-HSCT. 方法:應用常規細胞遺傳學方法定期檢測白血病患者異基因造血幹細胞移植前後常染色體、性染色體情況。
- X chromosome was the second largest submetacentric chromosome and Y was the smallest acrocentric chromosome in 1 pair sex chromosome. 1對性染色體中 ,X染色體為 1條第二大的亞中部著絲點染色體 ,Y染色體為最小的端部著絲點染色體。
- Methods Study the normal and sex chromosome by classic cytogenetic analysis in leukemia patients before and after treatment by allo-HSCT. 方法應用常規細胞遺傳學方法定期檢測白血病患者異基因造血幹細胞移植前後常染色體、性染色體情況。
- Results: Three of women patients had karyotype such as 46, XY showed donor s sex chromosome in 4 successful cases and primary abnormity disappeared. 結果:4例移植成功患者其中異性別3例性染色體表現為供者性染色體,原有異常消失;
- chemical resistant lethal mutation 抗藥性致死突變
- As we know ,the analysis of sex chromosome on ejaculated spermatozoa from the patient with a 46，XY/47,XXY by X/Y dual probe was reported for the first time in China. 這是國內第1例用雙色熒光原位雜交檢測46,XY/47,XXY少精子征患者精子性染色體的報告。
- Lincomycin - resistant lethal mutation 抗藥性致死突變
- The incidence of chromosome anomaly in hypospadias was higher than that of general population, and the majority of anomalies occurred in sex chromosome. 至於染色體異常發生的比率，則與尿道下裂開口位置嚴重程度，沒有互相關聯。
- Conclusion Identification of sex by FISH analysis of a single cleavage cell is accurate, and sex chromosome mosaicism will not affect preimplantation gender diagnosis. 結論 應用熒光原位雜交技術可準確地進行單細胞種植前性別診斷，性染色體嵌合型不會影響胚胎的性別診斷。
- The result showed that the ovary and brain aromatase gene of Nile tilapia was located on two different pairs of small chromosome other than the sex chromosome. 結果顯示，尼羅羅非魚卵巢和腦芳香化酶基因位於2對不同的小染色體上，而不是位於性染色體上。
- Abstract: Objective Using dual color fluorescent in-situ hybridization (FISH) to detect sex chromosome mosaicism in human embryos and perform preimplantation gender diagnosis. 文摘:目的應用雙色熒光原位雜交技術對人類早期胚胎性染色體嵌合型進行初步分析，並進行單細胞種植前性別檢測。
- But unlike humans, the X and Y are not sex chromosomes. 但是與人類不同的是，其X與Y染色體卻不是性染色體。
