In some carnations, flower color exhibits codominance. When crosses, Red (R) and white (W) flowers make speckled flowers (RW) that show both colors.
Complete a cross between A speckled flower and a red flower. Find the phenotype ratio.

• 2 red: 2 speckled: 0 white
• 4 red: 0 speckled: 0 white
• 0 red: 4 speckled: 0 white
• 0 red: 2 speckled: 2 white
