Answer:dominant trait =
* it is a trait which is able to express itsefl over another contrasting trait.
* it can express in both heterozygous and homozygous conditions.
recessive trait= * it is trait which is unable to express its effect in the presence of the dominant trait.
* it can express only in homozygous.
Cross between round (RR) and wrinkled (rr) pea plants
Parents RR cross rr
Gametes R r
F1 progeny Rr (round seed)
Selfing in f2 generation
R r
R. RR Rr
r. Rr rr
In f2 generation the progeny will be 75% round (RR, Rr)
25% wrinkled (rr)
