incomplete/ codominance

A roan cow shows co-dominance in fur color (orange and white). What is the phenotype ratio expected if a roan cow and a roan bull mate together?

• 4: Orange and White

• 1: Orange : 1 White

• 2 Orange: 2 Orange and White: 0 White

• 1: Orange: 2 Orange and White: 1 White

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

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
