When the Y chromosome from M. poschiavinus (YPOS) is transferred onto the C57BL/6J genome, XY individuals develop as females with 2 ovaries, or as hermaphrodites. No XY individual develops normal testes. Although C57BL/6J-YPOS XY females are rarely fertile, most hermaphrodites with normal male genitalia sire offspring. The M. poschiavinus Y chromosome carries a form of the Y-linked testis-determining locus different from that present in the C57BL/6J inbred strain. This gene interacts abnormally with autosomal or X-linked testis-determining loci of the C57BL/6J genome to prevent normal testicular differentiation. Divergence of the Y-linked testis-determining gene may be involved in mammalian speciation.
