A New autosomal trisomy in Turkman horse

In this study blood samples from Turkman horse were obtained. For the determination of chromosomes blood samples were used for metaphasal chromosome by the use of short term culture method. In this study the diploid model of Turkman horse was 2n=64 and from the 31 pairs of autosomal chromosomes , 8 pairs were metacentric, 5 pairs were submetacentric and 18 pairs were telocentric. The X and Y sex chromosomes were considered as submetacentric. In this study the diploid model for a 7 years old Turkman horse was found to be 2n=65. The extra chromosomes was the number 19 and this case was an example of autosomal trisomy. Using the G.banding technique, it was confirmed that the extra chromosomes is a homologue of pairs No: 19.
