When Morgan conducted dihybrid cross on Drosophila like Mendel did with pea plants,,

(a) Easy to grow (b) Short life span (c) Easily distinguishable characters (d) Larger size of flower (e) Self pollinated

(c) The genetic make-up of the tall parent can be depicted as TtWW Since all the progeny bore violet flowers, it means that the tall plant having violet flowers has...

Let C denote the set of people who like cricket, and T denote the set of people who like tennis  ∴ n(C ∪ T) = 65, n(C) = 40, n(C ∩...

(a) The dwarf traits of the plants is not expressed in the presence of the dominant tall trait. (b) In the F2 generation, both the tall and dwarf traits are present in...

1:2:1- Genotypic ratio

Flower colour / Flower position / Pod shape / Pod colour / Seed shape (Any two)

- When two genes in a dihybrid cross were located on the same chromosome they did not segregate independently  - The proportion of parental gene combinations were much higher than non...

Flower colour / Flower position / Pod shape / Pod colour / Seed shape

(i) Tall (ii) 3:1 (iii) Dwarf Reason: Being a recessive trait, dwarfness can only be expressed in the absence of dominant trait/ in its pure form.

(i) Mendel choose garden pea for his experiments because : (a) Pea plant is small and easy to grow (b) A large number of true breeding varieties of pea plant are available. (c)...
