Detailed Solution

(A) is true but (R) is false.

Assertion is true. Incomplete dominance is a form of intermediate inheritance in which the heterozygous phenotype (having two different alleles for a gene) appears as a blending or mixture of the phenotypes of the two homozygous parents. When a red-flowered parent (RR) is crossed with a white-flowered parent (rr) in certain plants, the resulting offspring (Rr) display a pink flower phenotype. The pink color is a blend of the red and white colors, illustrating incomplete dominance.

Reason is incorrect. In co-dominance, both alleles are expressed equally in the heterozygous individual.
