摘要：

The birth of live heterosexual quadruplets (three females and one male) in cattle (Bos indict's) is a very rare event and hence this study was conducted to observe the chromosome constitution of the darn and the heterosexual quadruplets. The cytogenetic study revealed sex chromosome chimerism (2n = 60, XX/XY) and preponderance of female cells (XX) in the heterosexual quadruplets, and the dam exhibited 2n = 60, XX chromosome complement. A high similarity of chimeric ratios was observed in all the calves and a relationship was also apparent between the chimeric ratio and the distribution of sex of fetuses.
