Gizmo Warm-upIt is intern Mark’s first day at the Fast Plants laboratory, and heis eager to impress.

Activity A:Creating ahypothesisGet the Gizmo ready:On theMystery parentmode, clickReset().Turn onAuto growandShow hints.Introduction:In this lesson you will look at the stem color and leaf color of Fast Plants®. Recallthat the stem color is controlled by two alleles:ANL(purple) andanl(green). The leaf color iscontrolled by the allelesYGR(green) andygr(yellow-green, which we will refer to as “yellow”).TheANLandYGRalleles are dominant, while theanlandygralleles are recessive.Question: What do the P1 and F1 phenotypes tell you about the P2 “father” plants?
