The best way to determine the genotype for a plant presenting with dominant phenotypes is by performing a test cross. Test crosses are always performed with a true-breeding plant with recessive traits. What would be the phenotype and genotype of the plant you would need to perform the test-cross with your tall, purple plant?After performing the test-cross with your unknown purple, tall plant you find that all your resulting plants are tall; half have white flowers, and half have purple flowers. What was the genotype of your original purple, tall plant?
