  A cross between a tall. plant (TT) and short pea plant (tt) resulted in progeny that were all tall plants because (a) tallness is the dominant trait                                                (b) shortness is the dominant trait (c) tallness is the recessive trait                                 (d) height of pea plant is not governed by gene T' or 't'

Answer:

                  (a) In  generation, the cross between TT and tt will result into all tall plants. Thus, tallness is the dominant trait. Whenever two traits of a character are crossed, the , plants show only one of the traits, this trait is called the dominant trait. The other trait (dwarfness in this case) that does not express itself in generation is called the recessive trait.
