Phenotype
In some carnations, flower color exhibits codominance. Identify the correct genotypes for red, white, and speckled carnations.
Red = RR, white = rr, speckled = SS
Red = RR, white = WW, speckled = SS
Red = RR, white = RW, Speckled = WW
Red = RR, white = WW, speckled = RW

All four would be brown and White
Half would be orange, half would be white
2 Brown: 2 Brown and White: 0 White
1 Brown: 2 Brown and White: 1 White
