Incomplete Dominance Question 2:Predict the offspring when two pink snapdragon flowers (RW) are crossed.b. What is the predicted phenotypic ratio for the offspring?(In Incomplete Dominance Phenotypic Ratio’s are written out by number and Phenotype:There is NO SPECIFIC ORDER)

A	1 Red:1 White:2 Pink
B	2 Red:1 White:2 Pink
C	1 Red:1 White:4 Pink

Explanation:

Detailed explanation-1: -Question 1: A cross between two pink snapdragons (RW x RW) should yield the following phenotypic ratio-1:2:1 (red, pink, white). 25% of the offspring are expected to be red so the calculation would be . 25 x 465 =116.25, which is rounded to the whole number 116.

Detailed explanation-2: -The pink flower color trait, which is an example of incomplete dominance, occurs in nature, such as those found in pink-flower-bearing angiosperms. Turns out the dominant allele is not expressed “completely” as shown in Figures 1 and 2 – incomplete dominance (Punnett square).

Detailed explanation-3: -So, the correct option is ‘Pink and white in 1 : 1 ratio’.

Detailed explanation-4: -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.
