Botany-Incomplete Dominance
NEET Botany Incomplete Dominance Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): In incomplete dominance, the F1 generation exhibits a phenotype that is intermediate between the two parent phenotypes. | Reason (R): In incomplete dominance, the genotype ratios match Mendelian monohybrid crosses, but phenotype ratios differ.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false, but R is true.
Correct Answer
Option A
Detailed Explanation
The NCERT context describes that in incomplete dominance, the F1 (Rr) is an intermediate phenotype (pink), and the genotypic ratios are Mendelian, but phenotypic ratios are altered from the dominant-recessive expectation.
