1. Saguaro cacti have 2 L-shaped arms and you have one with arms that are different lengths. Arm length in the cactus is controlled by one gene. Arms of the same length (A) are dominant to arms of a different length (a). What is the genotype of our cactus? If you cross our cactus with your neighbor’s cactus which has arms of the same length and ½ of the offspring have different length arms. What is the genotype of the neighbor’s cactus?

2. The ability to curl your tongue up on the sides (T, tongue rolling) is dominant to not being able to roll your tongue (t). A woman who can roll her tongue marries a man who cannot.
