What does “Law of dominance” actually mean in Principles of Inheritance and Variation, and why does it matter for NEET?
in a heterozygote only the dominant allele is expressed while the recessive one stays masked.
In simple words: in a heterozygote only the dominant allele is expressed while the recessive one stays masked. Getting Law of dominance clear matters because NEET questions on Principles of Inheritance and Variation usually test this idea directly, not just a formula you memorised.
Key point
Law of dominance
Common mistake
thinking the recessive allele is lost or destroyed in the F1.
Memory tip
the recessive allele is hidden, not lost -- it reappears in one quarter of the F2.
