Ah, that monohybrid cross—a textbook answer would tell you it's when you study one trait, like pea plant height, and the 3:1 ratio is the classic dominant-to-recessive outcome. But I remember just memorising those Punnett squares for exams, *bhala lagil* I could draw them perfectly. Now, teaching my own students, I see their same blank faces when we chant "phenotypic ratio three is to one," and I regret never explaining *why*—like how our old roof’s persistent leak doesn’t follow any neat ratio, no matter how many times I calculate the repair costs.
