Explanation:
Detailed explanation-1: -The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. This situation occurs due to the blending of both the alleles.
Detailed explanation-2: -A plant with red flowers is crossed with a plant with white flowers. The resulting offspring have pink flowers.
Detailed explanation-3: -∙Therefore, the offspring containing the genotype (Rr) will be red in colour. Was this answer helpful?
