Student Exploration: Fast Plants®– Mystery ParentDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Vocabulary:chi-squared test, degrees of freedom, deviation, dihybrid Punnett square, rosette-dwarfPrior Knowledge Questions(Do these BEFORE using the Gizmo.)In theFast Plants 1lesson you learned about two alleles for stem color.ANLis the dominant allele for purplestems, andanlis the recessive allele for non-purple (green) stems.Editand complete the Punnett square.Name:Jianna CapuanoDate:2-9-2021ANLANLanlANL/anlANL/anlanlANL/anlANL/anlYGRYGRygrYGR/ygrYGR/ygrygrYGR/ygrYGR/ygr1.TwoANL/anl100%
Gizmo Warm-upIt is intern Mark’s first day at the Fast Plants laboratory, and he is eager to impress. Hegathers pollen from a set of plants on one side of the room and carefully pollinates aset of plants on the other side. Then he goes out to lunch. When he returns, hissupervisor Pam compliments Mark on the great job he did pollinating the flowers. “So,where did the pollen come from?” Mark scratches his head in confusion. He knows itcame from somewhere over there, but which plants? He has no idea. “No problem,”says Pam. “We can figure it out from the offspring.”In theFast Plants 2 – Mystery ParentGizmo, you will use genetics to determine the identity of the unknownparent plant. To begin, select theMystery parentmode. Drag seed packetP1, the “mother” plants, tocontainer 1 andF1, the offspring plants, to container 2. ClickPlay(), and thenPause() after 10simulated days.Reproduction for educational use only.

Introduction:In this lesson you will look at the stem color and leaf color of Fast Plants®. Recall that the stemcolor is controlled by two alleles:ANL(purple) andanl(green). The leaf color is controlled 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?1.Grow: Plant theP1seeds in container 1 and theF1seeds in container 2. The F1 seeds are the offspring ofthe P1 mother plants and the mysterious P2 “father” plants. ClickPlay, and wait for the simulation to pauseon day 9.A.View the plants with themagnifying glass. Then, turn on theclipboard. Observe the results, thenturn onAdd class datato see simulated data from 1,000 plants.
