MONOHYBRID CROSS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a plant with red flowers (RR) is crossed with a plant that has white flowers ( WW), the resulting offspring has pink flowers ( RW). If two pink flowers are crossed, what is the probability of having a pink flower?
A
0%
B
25%
C
50%
D
75%
Explanation: 

Detailed explanation-1: -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-2: -The crossing of a red flowered plant and a white flowered plant, produces all the offspring with pink flowers.

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.

Detailed explanation-4: -Answer and Explanation: All (100%) of the offspring from the cross of a homozygous red-flowered plant with a homozygous white-flowered plant will have red flowers. We are told that the red flower is coded by the dominant allele.
