Three genes (A, B, and C) code for enzymes that together
produces purple colored corn kernels. If an offspring (kernel)
inherits two recessive alleles for any one of these three genes,
that kernel will be white. A corn plant with the genotype AaBbcc is
crossed with a corn plant with the genotype aaBbCc. What proportion
of the offspring of this cross will be white and what proportion
will be purple?
