UIC Eight Genes Were Mapped by Two Point Crosses Genes & Phenotypes Questions
Help with home work problem
Eight genes, designated cl, eb, gl, p, ry, sc, th and v were mapped by two-point crosses. For each pair of genes examined, the total percentage of non-parental phenotypes observed in a tes t cross of a F1 dihybrid female with a double-recessive male tester is given.

A. How many linkage groups are indicated by this data?
B. For each linkage group write the order of the genes and the distance between each gene.
Write your answer in the following format: geneA-#1-geneB-#2-geneC,
where gene A,B,C are the names of the genes in the correct order and #1,#2 indicates the distance between two genes with the correct units.
