Plain-English summary
Researchers found an unusual condition in a Spanish-bred horse that has both male and female traits, known as intersexuality. They discovered that this horse has an extra X chromosome, which is a genetic abnormality. This case is significant because it's the first time anyone has linked this specific genetic issue to intersexuality in any domestic animal.
Abstract
An X-trisomy has been detected in an intersexuality Spanish-bred horse by using G- and C-banding methods. The external characteristics and the behavioural and physiological irregularities of the horse are described. This is the first time that an association between an X-trisomy and a case of intersexuality has been reported in any domestic animal.
