Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A cross between a red rose and a white rose results in 100% pink roses. When pink roses are self-pollinated, the probable phenotypic ratio seen in their offspring would be ____

A	75% pink, 25% white
B	75% red, 25% white
C	100% pink
D	25% red, 50% pink, 25% white

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: -Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time.

Detailed explanation-3: -When a red flowered plant is crossed with a white flowered plant, ideally the offsprings should bear either red and white flower. However, in the case where the trait flower color exhibits incomplete dominance, all the offsprings will give forth pink colored flowers due to the blending of traits.

Detailed explanation-4: -The resulting offspring have pink flowers. What term describes the dominance of this trait? Explanation: A phenotypic “blending” of two traits is referred to as incomplete dominance, indicating that neither trait is truly dominant over the other.
