a.
Aa Bb Cc Dd EE
b.

2.
If you breed a black buck (aa BB CC DD EE) with a blue doe (aa BB CC dd ee),
what color will the genes of the offspring be? What would the color of the
offspring be?
3.
Make a Punnett square for the following cross. AaBb X AaBb. What is the
expected color ratio of the offspring? (Use the color handout and assume that the
B,C, and E genes homozygous dominant.)
4.
A white buck is bred to 5 does with known genetics. The offspring are the
resulting colors. What is the white bucks genetic code? Use Punnett squares to
help solve the problem. (Hint: Do each doe as a seperate problem.)
