Law of Dominance in Monohybrid Cross — NEET Biology
📚 Practice ConceptExplain the Law of Dominance using a monohybrid cross.

View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT confirms law of dominance explains monohybrid inheritance (Assertion true). However, NCERT states the law “is used to explain the expression of only one of the parental characters in a monohybrid cross in the F1” - the Reason falsely claims blending rather than expression of only one character, making it false. Tests understanding that dominance involves masking, not blending.
