Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A red flowered plant (RR) breeds with a white flowered plant (WW). The gene for petal color in these plants expresses incomplete dominance. What percentage of the offspring will have pink (RW) flowers? Use a Punnett square to answer.
A
0%
B
25%
C
50%
D
100%
Explanation: 

Detailed explanation-1: -∙Therefore, the offspring containing the genotype (Rr) will be red in colour. Was this answer helpful?

Detailed explanation-2: -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-3: -Answer and Explanation: If a white flower is crossed with that of a red flower, and all of the offspring are red flowers. This would indicate that the white flower has a homozygous recessive genotype.

Detailed explanation-4: -The example of codominance can be seen in plants with white color as recessive allele and red color as dominant allele produce flowers with pink and white color (spots) after cross-breeding.
