Mendel crossed a pure tall pea plant (TT) with a pure short pea plant (tt) and obtained all tall plants in generation.
(a) What is the gene combination present in the plants of generation?
(b) Give reason why only tall plants are observed in progeny.
(c) What will be the ratio of the plants obtained in the generation when plants are self-pollinated?

(a) What is the gene combination present in the plants of generation?
(b) Give reason why only tall plants are observed in progeny.
(c) What will be the ratio of the plants obtained in the generation when plants are self-pollinated?
(a) The gene combination present in the plants of generation is Tt.
(b) Only tall plants are observed in progeny because the tall allele (T) is dominant over the short allele (t).
(c) The ratio of the plants obtained in the generation when plants are self-pollinated is 3:1 (3 tall: 1 short).
