RESUMEN

A través del análisis citogenético se diagnosticaron como freemartin cinco individuos seleccionados de un total de 10 bovinos (Bos taurus) que tenían el antecedente de proceder de partos múltiples heterosexuales; asimismo, se estudiaron anatomopatológicamente dos de estos individuos. La presencia de quimerismo cromosómico (60,XX/60,XY) caracterizó a los animales estudiados, excepcionalmente un individuo freemartin mostró tan sólo células 60,XY, en tanto que los hallazgos anatomopatológicos de dos freemartins estudiados hasta su sacrificio exhibieron masculinización del tracto reproductor con únicamente tejido testicular en las gónadas.
