In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow kernels. At a second gene, W– produces smooth kernels, while ww kernels are wrinkled. A plant with blue smooth kernels was crossed to a plant with yellow wrinkled kernels. The progeny consisted of 1447 blue smooth, 169 blue wrinkled, 186 yellow smooth, and 1510 yellow wrinkled.

a. Are the a and w loci linked? If so, how far apart are they?
b. What was the genotype of the blue smooth parent? Include the chromosome arrangement of alleles
c. If a plant grown from a blue wrinkled progeny seed is crossed to a plant grown from a yellow smooth F, seed, what kinds of kernels would be expected, and in what proportions?
