Dominance Recessive

A dominant factor or allele expresses itself in the presence or absence of a recessive trait.

 A recessive trait is able to express itself only in the absence of a dominant trait.

For example, tall plant, round seed, violet flower, etc. are dominant characters in a pea plant.

 For example, dwarf plant, wrinkled seed, white flower, etc. are recessive traits in a pea plant.
