Two pure-breeding wheat strains, one producing dark red kernels and the other producing white kernels, are crossed to produce F1 with pink kernel color. When an F1 plant is self-fertilized and its seed collected and planted, the resulting F2 consist of 160 plants with kernel colors as shown in the table.

A: Based on the F2 progeny, how many genes are involved in kernel color determination?
   Answer: 2
B: How many additive alleles are required to explain the five phenotypes seen in the F2?
   Answer: 4
C: If alleles that add to kernel pigment are designated with a "1", and alleles that do not add to kernel pigment are designated with a "2", enter the genotypes for the dark red parent and then the genotype for the white parent.
   Answer: A2A2B2B2 and A1A1B1B1
D: Give genotype(s) for the F1.
   Answer: A1B1A2B2
E: What will be the color of the F1 ?
   Answer: Pink
