[Intersexuality in the horse. Morphologic, hormone analytic and cytogenetic studies in an Arabohaflinger horse].
A case of intersexuality in an arabo-haflinger horse is described. The external genitalia consisted of mammary gland, vulva and hypertrophic clitoris; the inner genitalia of rudimental testes. The sexual behaviour was typically male-like. The chromosome analysis showed the female karyotype 64,XX. The presence of testes in a genetically female animal is explained by translocation of an Y-chromosome fragment bearing the gene for the H-Y-antigen.
