Male-restricted expression of H-Y antigen on preimplantation mouse embryos
The H-Y (male) antigen is detectable on 50% of eight-cell mouse embryos. We show that 82% of the offspring resulting from the transfer of (C57BL/6 X A/J)F1 embryos surviving treatment with H-Y antibody and complement to the uteruses of pseudopregnant mice are female. The increased ratio of female-to-male births indicates that the H-Y-bearing embryos are male.
