Karyotypes of the female and male Andrias davidianus have been observed by blood cell culture and chromosome preparation methods.

采用外周血培养和制备染色体标本的方法，分析雌雄中国大鲵的核型特征。

The data show that:(1) The chromosome number of Andrias davidianus is 2n=60.(2) The karyotype consists of macrochromosomes and microchromosomes.(3) In macrochromosomes, eight pairs are metacentric and two pairs are submetacentric.(4) Andrias davidianus has 20 pairs of microchromosomes, among which are four pairs of bi-armed chromosomes. They are No.11, No.25, No.23 and No.24. Other microchromosomes are telecentric.
