Abstract

A Cytogenetic studies were performed in 4 pairs of heterosexual bovine twins and 2 freemartin. The cell samples permitted to analyze the sexual quimerism XX/XV. Samples of XY cells in the twins did not show significative differences (x²=4.72; p<O.2), so a parallel variation is postulated. A total bidirectional interchanged of lymphocytes through the vascular anastomosis is determinated. A random distribution of XY cells in each case is shown.
