Consider that a plant with genotype RR has red flowers and a plant with genotype WW has white flowers. This plant species expresses incomplete dominance for flower color when the plant is heterozygous.

Question

The offspring of a cross between an RR plant and a WW plant would be
(1 point)
• red and pink.
• all pink.
• pink and white.
O all white.

Answer 1

In the case of incomplete dominance, when a plant with genotype RR (red flowers) is crossed with a plant with genotype WW (white flowers), the offspring (F1 generation) will have the genotype RW, which exhibits a blend of the two parental traits. In this case, the color expressed would be pink.

Therefore, the offspring of a cross between an RR plant and a WW plant would be:

• all pink.
