Parts and their functions

• Parents: TT × tt (जनक: TT × tt) — A pure tall plant crossed with a pure short plant.
• F1: all Tt, all tall (F1: सभी Tt, सभी लंबे) — No medium plants — tall (T) is dominant, so Tt looks tall.
• F2: 1 TT : 2 Tt : 1 tt (F2: 1 TT : 2 Tt : 1 tt) — Self-pollinated F1 gives 3 tall : 1 short.
• Short plant reappears (tt) (बौना पौधा फिर दिखा (tt)) — Shortness was hidden in F1, so it is recessive; it shows only when both copies are t.
