Solutions For An Introduction to Genetic Analysis Chapter 15 Problem 2P

In the above figure, we compare the phenotype of the chromosome breaking strain with the phenotype of one of the derivative strains. The chromosome that loses the wild type alleles of the C, Sh, Wx genes produces the large sector of mutant tissue, which displays the loss of expression of all the three genes.

If the strain is homozygous for all dominant markers, the dominant traits would be expressed on the phenotype of the kernels, which will be pigmented, plump, and shiny.
