Q.
A cross between a tall plant (TT) and short pea plant (tt) resulted in progeny that were all tall plants because:

1 Tallness is the dominant trait

2 Shortness is the dominant trait

3 Tallness is the recessive trait

4 Height of pea plant is not governed by gene ‘T’ or ‘t’

Ans.
(1)

When two traits of a character are crossed, the $F ₁$ plants only show one of the two traits, which is known as the dominant trait. The recessive trait (dwarfness) is a trait that does not manifest itself in the $F ₁$ generation
