4. How would you expect the numbers of offspring from a typical trihybrid
backeross to look if you have two linked loci and one loci that is independently
assorting?
5. In certain instances crossing over between two linked genes can be suppressed.
For example, this can occur when one chromosome has an inversion. How would
crossover suppression affect your results if you were trying to map two genes?
6. The gene order for four genes (p,q.r s) is shown below with the map distances
between them. How many of 4500 offspring would you expect to have undergone
a crossover between q and r?
