染色体显带技术的产生使人们能对人类２４条染色体（１～２２，Ｘ，Ｙ）进行识别和鉴定，而且近年来已经可以通过计算机软件进行自动核型分析。１９９６年以来在萤光原位杂交（ＦＩＳＨ）技术的基础上由两个研究组分别推出了十分相近的一种核型分析新技术———彩色光谱核型分? Chromosome banding technology allows people to human chromosome 24 (1 ~ 22, X, Y) identification and identification, and in recent years has been available through computer software karyotyping. Since 1996, based on fluorescence in situ hybridization (FISH) technology, two research groups have respectively introduced a very similar karyotype analysis technique --- color spectrum karyotype analysis,
