The results showed that the number of normal diploid chromosomes was in the alpacas 2n=74. Additionally, several types of chromosome aberrations were observed in somatic cells of the normal alpacas. These aberrations involved triploid, tetraploid and ring chromosomes. But their aberration frequencies were very low.展开更多
