16. Quiz What is the genotype? What is the phenotype? White

17. Quiz What is the phenotype? What is the genotype?

19. aleurone The aleurone is a coating over the corn kernel. If the aleurone is purple it masks the color of the inside of the kernel. Figure out if the gene for purple is dominant or recessive.
