2019Name:Date:Student Exploration: Fast Plants®2Mystery ParentNote to teachers and students: TheFast Plants®Gizmo was created in collaboration withWisconsin Fast Plants. TheFast Plants 2Mystery Parentlesson was designed as a follow-upto theFast Plants 1Growth and Geneticslesson.Vocabulary:chi-squared test, degrees of freedom, deviation, dihybrid Punnett square,rosette-dwarfPrior Knowledge Questions(Do these BEFORE using theGizmo.)In theFast Plants 1lesson you learned about two alleles forstem color.ANLis the dominant allele for purple stems, andanlis the recessive allele for non-purple (green) stems.1.TwoANL/anlplants are crossed. What percentage ofthe offspring plants will have purple stems?2.AnANL/anlplant is crossed with ananl/anlplant. Whatis the percentage of purple-stem offspring now?Gizmo Warm-upIt isintern Mark’s first day at the Fast Plants laboratory, and heis eager to impress. He gathers pollen from a set of plants onone side of the room and carefully pollinates a set of plants onthe other side. Then he goes out to lunch. When he returns,his supervisor Pam compliments Mark on the great job he didpollinating the flowers. “So, where did the pollen come from?”Mark scratches his head in confusion. He knows it came fromsomewhere over there, but which plants? He has no idea. “Noproblem,” says Pam. “We can figure it out from the offspring.”In theFast Plants 2Mystery ParentGizmo, you will use genetics to determine the identity ofthe unknown parent plant. To begin, select theMystery parentmode. Drag seed packetP1, the“mother” plants,to container 1 andF1, the offspring plants, to container 2. ClickPlay(), andthenPause() after 10 simulated days.What are the traits of the P1 and F1 plants?
2019Activity 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.
