  1. aParental sources of the X chromosomes are indicated (Xm: maternal; Xp: paternal)
  2. bFigure 3 includes the structure and gene content of the Y*X chromosome
  3. cOn a B6 background, these females die in utero [75]
  4. dThese XmXpY*X females are mated to XYˉSry males in order to produce the XYˉY*X Sry males used for Cross B (see Additional file 1)
