  1. $100\%$ ovules will have $XXX$ endosperm and $XX$ embryo
  2. $100\%$ ovules will have $XXY$ endosperm and $XY$ embryo
  3. $50\%$ ovules will have $XYY$ endosperm and $XY$ embryo, while other $50\%$ will have $XXY$ endosperm and $YY$ embryo
  4. $50\%$ ovules will have $XXX$ endosperm and $XX$ embryo, while the other $50\%$ will have $XXY$ endosperm and $XY$ embryo
