1. Mendel's peas are boring. Make up a different example (they can be imaginary traits) and
show the results of a dihybrid cross that follows Mendel's rules. Make sure to designate
which trait(s) are dominant vs. recessive. The parents in P? must be true breeding either for
the dominant or recessive traits (show their genotypes). Using a Punnett square, show the
genotypic and phenotypic ratios of the F? generation. Draw (illustrate) and classify the
phenotype of the organism for each of the 4 different phenotypes. Points for artistic merit!
2. List which antigens (A, B, Rh) and antibodies (anti-A, anti-B, anti-D) are produced and which blood
types (include both ABO and Rh groups) are compatible for transfusion for each blood type (6 pts):
Blood type Antibodies produced
A+
B-
AB+
O-
Antigens present
Compatible Blood
