Abstract
In the case of unlike-sexed twins in cattle, freemartinism, although v ery likely, can not be diagnosed in the young calf by a clinical exami nation. Leucochimerism, as a consequence of vascular anastomoses betwe en the two fetuses, can be revealed at birth by DNA fingerprinting. Th e Polymerase Chain Reaction (PCR) on a bovine Y-specific sequence is a quick and sensitive method in detecting XX/XY chromosomal chimerism.
