If a red-flowering plant was crossed with a white-flowering plant what would the phenotypes of the offspring be?

Well if both are dominate colors the phenotype of the offsprings would be pink or spotted. if the red flowering plant was dominate and the white flowering plant is recessive then the phenotype would be 100% red, they would just be the carrier of the white color. if the white flower is dominate and the red is recessive the flowers phenotype would be 100% white, but be carriers of the red color.
