Mendel's Law of Dominance — NEET Biology
🔥 Predicted for NEET 2027Characters are controlled by discrete units called factors. (ii) Factors occur in pairs. (iii) In a dissimilar pair of factors one member of the pair dominates (dominant) the other (recessive). The law of dominance is used to explain the expression of only one of the parental characters in a monohybrid cross in the F₁ and the expression of both in the F₂. It also explains the proportion of 3:1 obtained at the F₂.

Q2. Why did Mendel not observe blending of traits in the F₂ generation of the dihybrid cross?
View solution & NCERT explanation
Correct answer: B — Because traits are inherited in discrete units (alleles)
Mendel demonstrated that traits are controlled by independent units (alleles), which do not blend but reappear in segregation.
