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 recessive genes in dogs are linked on a chromosome. A dog heterozygous for all three recessive alleles is crossed with homozygous for all the recessive alleles in a three-point testcross. (a) Determine the order of these genes on the chromosome and (b) calculate the map distances between the genes. The progeny of the testcross are: r    T    W                 324 R    t   w                 319 R   t    W                880 r   T     w               887 R    T   W                2376 r    t     w                 2365 r   t     W                47 R    T     w                41 Total      7,239

True or False When genes are on the same chromosome, the alleles on one of the two homologous chromosomes are considered to be in trans. Two genes can be syntenic and unlinked. If recombination rate is high, then a particular combination of alleles is likely to be transferred to the next generation intact.

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...
