To detect the patients and carriers of the fragile x syndrome , various analytic methods could be used . one is cytogenetic diagnosis to observe the expression of the fragile site fraxa located at xq27 . 3 对脆x综合征的诊断，可以通过细胞遗传学方法观察分析x染色体相应脆性位点的表达情况，或是通过southern印迹杂交的方法直接分析cgg重复的扩增突变。
The best possible treatment outcome ? a complete cytogenetic response , which is the elimination of the genetic abnormality associated with the disease ? occurred in 57 percent of the study participants and was achieved in a median time of eight months 最好的可能治疗结果是完全细胞遗传学缓解，即疾病相关基因异常的排除，在57 %的研究对象身上出现，出现的中位时间为8个月。
Progress of genetic studies on phosphorus efficency in wheat was summarized in this paper , including defenition of phosphorus efficency , cytogenetic research , differences between different genotypes , correlation with other traits , and molecular markers 摘要综述了小麦磷效率遗传学领域的研究进展，包括磷效率的含义、细胞遗传学研究、基因型间的差异、与其它性状的相关性、分子标记等。
The cytogenetic tests deal with all chromosomal analysis for different diseases . the molecular tests investigate about 40 genetic diseases and the biochemical tests mainly investigate enzymes and proteins products of genetic diseases 细胞染色体分析对不同疾病进行染色体分析，分子遗传学检验对大约40种的遗传疾病进行测试，而生化遗传检验则主要检验病人体内酵素及蛋白质的含量，以测试有关的遗传疾病。
