1. A dihybrid cross with complete dominance in both genes involves a pure-bred variety of round, green peas crossed with a pure-bred variety of wrinkled, yellow peas.

A. 1:2:1:2:4:2:1:2:1 B. 3:1:3:1:3:1:3:1 C. 1:2:1:1:2:1 D. 9:3:3:1 E. 1:1:1:1 2. What is the probability that flipping five coins (one penny, one nickel, one dime, one quarter, and one half-dollar) will result in four "heads" and one "tail"?
