As the ration neither matches with 1:1:1:1:1:1:1:1 nor mathces with triple point test cross ratio, which indicates what two genes are linked and one gene is present on another chromosome.

So, the steps involved in this problem is
1. Seperation of crosses per pair of genes (such as between d and e genes; e and g genes and d and g genes)
2. Genotypes and freequencies interpretation
3. Ratio comparisions (If the ratio indicates 1:1:1:1 ratio, dihyrbid test cross ratio, which means that two genes are present on two different chromosomes. If the ratio not indictes 1:1:1:1 which means that two genes are present on same chromsomes)

Three genes with recessive mutant phenotypes are located on the same chromosome in maize: short stem (ss), purple aleurone (pr), and knotted leaf (kn). A plant with all three mutant phenotypes is crossed with a true-breeding, wild-type plant. Resulting F1 plants are then backcrossed to the parental mutant line to produce the following progeny:   (7 points) Short        Purple     Knotted       Number ss                       +                  kn                   2342 +                        pr                 +                    2297 ss                       pr                 kn                   4095 +                        +              ...

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...
