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.
