第一个发现的雄激素性秃发易感基因-雄激素受体基因，位于X染色体上；另外，位于Y染色体上的性别决定基因、常染色体上的脱发基因等也与雄激素性秃发发病有关。

Blood samples from 23 Huacaya alpacas ,3 males and 20 females ,were used to study chromosome karyotype ,so as to provide some effective cytogenetics basis for the selectioiymprovement by crossing and disease diagnosis of alpacas ,and genetic mechanisms of sex determination. Peripheral blood lymphocyte culture was used to prepare chromosome. Methods of trypsase-EDTA and BSG (Barium hydroxide / Saline / Giemsa)were used for G-banding and C-banding respectively . The results showed as follows:Firstly , the number of diploid chromosomes was in the alpacas 2n=74,with the karyotype 74, XY and 74, XX for males and females respectively.

为了从选种、杂交改良、疾病诊断以及性别决定的遗传机制等方面为羊驼的繁育与推广提供更为有效的细胞遗传学资料，本试验采用外周血淋巴细胞培养法制备染色体，分析了23只胡阿基亚型羊驼(Huacaya alpaca，雌20只，雄3只)的染色体及其核型，并通过BSG法(Barium hydroxide／Saline／Giemsa，氢氧化钡-盐溶液-吉姆萨，也即Sumner BSG法)与胰酶-EDTA法分别对羊驼的C-分带和G-分带进行分析，结果表明：(1)羊驼二倍体染色体数目为2n=74，雄性羊驼核型为74，XY；雌性羊驼核型为74，XX。

Due to the breakthrough of stained technology in 1970s, the band-pattern of chromosome provides material visual information for cytogeneticist, then analyses the composition of genome in a cell and measures the features of the equipments for karyotyping.In order to meet the demands of clinical hospital, a chromosome analysis system based on PC is developed.

由于70年代标本染色技术的突破(取代了此前的均匀染色方法，产生了染色体的带型特征)，染色体的带型模式为细胞遗传学家提供了实质性的视觉信息，从而可以进一步分析细胞的基因组的合成以及进行自动核型分类仪器中的特征测量。

Fig 1 The results of two color FISH A:Normal sperms(a sperm nucleus with a red fluorescence domain was X sperm, and with a green fluorescence domian was Y sperm);B:Numeric chromosome abnormal sperm two green fluorescence domains within the same sperm nucleus which may be classified in Y disomic sperm or diploidy sperm, in the case of hybridization with two probes, one euchromosome specific and the other sex chromosome specific, this sperm could be discriminated as disomic or diploidy sperm

图1 双色荧光原位杂交结果 A：正常精子(精子头部有1个红色荧光信号者为X精子，有1个绿色荧光信号者为Y精子)；B：染色体数目异常精子两个绿色荧光信号同在1个精子核内，可为Y双体精子或二倍体精子，若用1条常染色体探针和1条性染色体探针进行双色荧光原位杂交，可以区别该精子属Y双体精子或二倍体精子
