. In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aaplants have yellow kernels. At a second gene, W–produces smooth kernels, while ww kernels are wrinkled. A plant with blue smooth kernels was crossedto a plant with yellow wrinkled kernels. The progenyconsisted 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 apartare 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 seedis crossed to a plant grown from a yellow smoothF1 seed, what kinds of kernels would be expected,and in what proportions?
