To solve this problem, we need to analyze the genetic experiment described and identify the incorrect statement. Let's break down the information:$\newline \bullet$In Antirrhinum (Snapdragon), a red flower was crossed with a white flower, resulting in pink flowers in the F1 generation.$\newline \bullet$This indicates that neither red nor white is completely dominant, leading to a blending of traits, known as incomplete dominance.$\newline \bullet$When the F1 pink flowers were selfed, the F2 generation showed a phenotypic ratio of 1/4 red, 1/2 pink, and 1/4 white.$\newline$Now, let's evaluate each statement:$\newline \bullet$Option 1: This experiment does not follow the Principle of Dominance.$\newline$ - This is correct because incomplete dominance is observed, where neither allele is completely dominant.$\newline \bullet$Option 2: Pink color in F1 is due to incomplete dominance.$\newline$ - This is correct as the blending of red and white results in pink, demonstrating incomplete dominance.$\newline \bullet$Option 3: Ratio of F2 is 1/4 (Red) : 1/2 (Pink) : 1/4 (White).$\newline$ - This is correct as it matches the expected phenotypic ratio for incomplete dominance.$\newline \bullet$Option 4: Law of Segregation does not apply in this experiment.$\newline$ - This is incorrect because the Law of Segregation applies to all Mendelian inheritance patterns, including incomplete dominance.$\newline$Therefore, the incorrect statement is Option 4.
