近十年来人类遗传学发展迅速,过去对某些染色体的识别较为困难,1969年以后开展了染色体显带技术,因而能将人类23对染色体明确地予以区分。1976年以后人类染色体高分辨法的建立使细胞遗传学的研究又向前推进了一步,为人类基因定位创造了有利条件。目前运用家系调查连锁分析、种间体细胞杂交、限制性内切酶及染色体重排畸形等方法已能将不少基因定位于特定染色体
The rapid development of human genetics in the past decade, the past, some of the chromosomes more difficult to identify, carried out after 1969, chromosome banding technology, which can be 23 human chromosomes clearly distinguish. Since 1976, the establishment of high-resolution human chromosomes has pushed cytogenetic research one step further and created favorable conditions for human gene mapping. At present, using the methods of pedigree linkage analysis, interspecific somatic hybridization, restriction endonucleases and chromosomal rearrangement and deformity, many genes have been mapped to specific chromosomes
