Type I questions: 1. In gorgonzolas, there are three recessive traits that affect the organism's appeal: shrunken fruit, foul-smelling flowers, and short height. A heterozygote was crossed with a homozygote, yielding the following offspring: 46 - foul-smelling 44 - shrunken fruit, short height 8 - short height 8 shrunken fruit 7- foul-smelling, short height 6- foul-smelling, shrunken fruit 3 - foul-smelling, shrunken fruit, short height 1 - normal phenotype Determine the genetic map for these traits, showing map distances.

Construct a map of the linked genes.
3. The allele b gives Drosophila flies a black body and b+ gives brown, the wild-type phenotype.
The allele wx of a separate gene gives waxy wings and wx+ gives nonwaxy, the wild-type
phenotype. The allele cn of a third gene gives cinnabar eyes and cn+ gives red, the wild-type
phenotype. A female heterozygous for these three genes is testcrossed, and 1000 progeny are
classified as follows: 5 wild type; 6 black, waxy, cinnabar; 69 waxy, cinnabar; 67 black; 382
cinnabar; 379 black, waxy; 48 waxy; and 44 black, cinnabar. Are these three genes linked? If
so, draw a map of the chromosomes in the heterozygous parent, showing the order, arrangement,
and map distance between the linked genes.
