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.

结果表明：(1)中国大鲵染色体数目为2n=60；(2)染色体由大染色体和微小染色体组成，属于两型性染色体；(3)大染色体中有8对中部着丝粒染色体和2对亚中部着丝粒染色体；(4)微小染色体有20对，大多是端部着丝粒染色体，在雌性中发现了4对双臂染色体，第11、25号是亚中部着丝粒染色体，第23、24号是中部着丝粒染色体。

但本实验结果显示，大鼠孕期和哺乳期接触达母体中毒剂量的硫丹，对雄性子鼠的睾丸重量、每日精子生成量、附睾精子数和精子形态、睾丸生殖细胞凋亡发生率等都没有明显的影响，也未见雄性子鼠AGD缩短、乳头残留及隐睾和尿道下裂等雌性化表现。

The data showed that during non mating season the frequencies of rubbing anogenital, sniffing and urinating/defecating in sexually active males were remarkably higher than those in the sexually inactive ones, and the frequencies of investigating, sniffing and urinating/defecating of sexually active females were significantly lower than those of the sexually inactive ones.

结果表明：在非交配季节，性活跃雄性蹭阴、嗅闻和尿粪标记频次显著多于性不活跃雄体；性活跃雌性活动、探究、嗅闻和尿粪标记频次显著低于性不活跃雌体。
