Pure-tall (TT) pea plants are crossed with pure-dwarf (tt) pea plants. The pea plants obtained in F1 generation are then self-pollinated to produce F2 generation.
(i) What do the plants of F1 generation look like? Justify your answer.
(ii) What is the ratio of pure-tall plants to pure-dwarf plants in F2 generation?
Proteins control the expression of various characters. Explain this statement by taking an example of "tallness" as a characteristic in plants
In the adjoining figure, $\triangle CAB$ is a right triangle, right angled at A and $AD \perp BC$. Prove that $\triangle ADB \sim \triangle CDA$. Further, if $BC = 10$ cm and $CD = 2$ cm, find the length of AD.
