Examining the animals genes, Ornitz and colleagues discovered that half of the mice were indeed genetically male, even though they had underdeveloped testes or lacked any male reproductive organs. "We c......ected bone marrow cells from normal male mice into newborn female mice that had no white blood cells of their own. Using marrow from male mice allowed the researchers to use the Y chromosomes in the transplanted cells as a marker to distinguish them from native cells.
