Two different varieties of a plant were used to study their genetics. After cross breeding them for many generations ,it was found that the red colour of fruit endosperm is dominant over white colour of fruit endosperm. If plant is selected at random from the progeny with red fruit endosperm how will you determine the genotype of that plant?
