Paull BIO 212 Problem Set #6 (15 pts) Due on March 10/11 Handout #6: dihybrid cross/extensions to Mendel 1. (2 pts) Imagine two unusual character traits in cats: 7 toes instead of 5, and baldness on the head. Both traits are dominant. If you cross a 7-toed, bald cat with a normal hairy cat, what are the possible outcomes? (There are 4 different scenarios; list the genotypes and phenotypes of the offspring for each scenario using A and a for toes and B and b for baldness) AABB x aabb = AaBb AaBB x aabb = AaBb + aaBb (7toed and bald + Normal and bald) AABb x aabb = AaBb + Aabb (7toed and bald + 7toed and hairy ) AaBb x aabb = AaBb + aaBb + AaBb +aabb (7toed and bald + normal and hairy + 7toed and bald + normal and hairy ) 2. (5 pts) In sesame plants, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant to wrinkled leaf (l). Pod type and leaf type are inherited independently. Determine the genotypes for the two parents for all possible
