Go through questions 1-9 of the tutorial. If you answer any question incorrectly, review the tutorial material and try again.

When you have completed this much of the tutorial, answer the questions below:

1. What type of gametes will be produced by a plant of genotype AaBb?

            a. The type of gametes that will be produced by a plant of genotype AaBb is AB,Ab,ab, and aB

2. What type of gametes will be produced by a plant of genotype aabb?

            a.the type of gametes that will be produced by a plant of genotype aabb would be ab.

3. List all the genotypes you would find among the offspring of an AaBb x aabb test cross.

            a.AB,ab,Aa,Bb,Ab,Ba

4. What is the expected phenotypic ratio of the offspring of an AaBb x aabb test cross?

            a.1/16

5. List all possible gametes from a trihybrid individual whose genotype is RrSsTt.

a.RS,ST,RT,rs,rt,st,St,Rs,Tr,Ts,Rt,Sr
