Anirudh wanted to know the genotype of a pea plant in his kitchen garden that had violet flowers. To do this, he crossed the violet - flowered plant, with a white flowered plant, resulting in all plants with violet flowers. When these plants were self-pollinated, 75 violet - flowered plants and 22 white - flowered plants were produced. Now, he knows the genotype of the violet - flowered plant and can confirm it by crossing it with a white - flowered plant.
