24. In a plant, the colour of grains is controlled by 3 genes located on separate chromosomes. Gene 'C' and 'R' independently do not form any colour, but when together, they impart greenish-brown colour to the stem, while the grains remain colourless. In presence of an additional allele 'A', the stem as well as grains become violet. In a trihybrid cross, what phenotypic ratio is expected in grains?
