Mendel crossed a pure tall pea plant (TT) with a pure short pea plant (tt) and obtained all tall plants in F1 generation.
(a) What is the gene combination present in the plants of F1 generation ?
(b) Give reason why only tall plants are observed in F1 progeny.
(c) What will be the ratio of the plants obtained in the F2 generation when F1 plants are self-pollinated ?
Solution
(a) Tt
(b) Because only Dominant trait (Tall) is expressed in F1 generation / Tallness is dominant over recessive short trait.
(c) F2 generation – Tall : short
3 : 1
