n corn long ears (L) is dominant to short ears (l); glossy kernels (G) is dominant to opaque kernels (g) and high starch (S) is dominant to normal starch (s). A heterozygous plant with long ears, glossy kernels and high starch is crossed with a short eared plant with opaque kernels and normal starch. The following phenotypes are observed. Which genes are linked? (Gene name is based on the dominant trait.)
