In a pea plant, a gene R produces red flowers and is dominant to a gene r, which produces white flowers.?

A gene T produces tall plants and is dominant to a gene t for short plants. If a plant that is homozygous for red flowers and heterozygous for tallness is crossed with a plant that is short and white, what will be the phenotypic ratio of the parents?


A. one tall red: one short red


B.nine tall red:three short red:three tall white:one short white


C. three tall red: one short red: one tall white


D. one short white: two short red: one tall white

In a pea plant, a gene R produces red flowers and is dominant to a gene r, which produces white flowers.?
A





The cross is RRTt X rrtt





All offspring will have red flowers, but half will be tall (Tt) and half will be short (tt).
