• Incomplete Dominance

• Codominance

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross a red flower with a speckled flower. What is the phenotypic ratio?

• 2 red, 2 speckled

• 2 red, 2 blue

• 2 blue, 2 speckled

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

• Incomplete Dominance
• Codominance

• Independent assortment
• Recessive inheritance

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

Radish color is completely dominant, red and white are pure breeding colors. While heterozygous are purple.

Cross a red radish with a white.
