What does “Monohybrid ratio” actually mean in Principles of Inheritance & Variation, and why does it matter for NEET?

a cross of one trait gives a 3:1 phenotype ratio in the F2 generation.

In simple words: a cross of one trait gives a 3:1 phenotype ratio in the F2 generation. Getting Monohybrid ratio clear matters because NEET questions on Principles of Inheritance & Variation usually test this idea directly, not just a formula you memorised.

Key point

Monohybrid ratio

Common mistake

confusing the 3:1 phenotype ratio with the 1:2:1 genotype ratio.

Memory tip

3:1 is what you SEE; 1:2:1 is the underlying genotype.
