In some carnations, flower color exhibits codominance.  Identify the correct genotypes for red, white, and speckled carnations.

• Red = I^RI^R, white = I^rI^r, speckled = I^RI^r

• Red = I^RI^R, white = I^WI^W, speckled = I^rI^w

• Red = I^RI^R, white = I^wI^w, Speckled = I^RI^w

• Red = I^RI^R, white = I^WI^W, speckled = I^RI^W
