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.
