A zebrafish that is a triple heterozygote for the three linked genes is test-crossed to generate a linkage map. The wild-type phenotypes are golden (gol+), stripe (st+), and bug-eye (be+). The mutants are gol, st, and be, and a dot between the alleles indicates that their relative positions are not known. gol+ · st+ · be 382 gol · st · be+ 379 gol+ · st · be 69 gol · st+ · be+ 67 gol+ · st · be+ 48 gol · st+ · be 44 gol+ · st+ · be+ 6 gol · st · be 5 A. What was the genotype of the starting female fish? (10p) B. Draw the linkage map, showing the correct order of the genes and the recombination frequency between them. (30p) C. What is the interference? (10p)
