Abstract
- A routine parentage test as part of a conservation program for Kiso horses identified a possible sex chromosome anomaly in a 7 months-old filly because of an aberrant result using LEX3, an X-linked marker. We then analyzed X-linked markers (LEX26, TKY38, and TKY270), Y-linked markers (Eca.YH12, Eca.YM2, Eca.YA16, and the sex-determining region Y gene), and an X/Y marker (Amelogenin gene). This analysis demonstrated that the filly had not inherited an X chromosome from her sire. A karyotyping analysis confirmed that the filly was 63, XO. As it was suspected that the horse would be sterile, we avoided using the horse as a broodmare; the information should also serve to prevent unnecessary conflict between owners transferring and receiving the horse.
