Name:John KimDate:2/14Student Exploration: Fast Plants®2 – Mystery ParentDirections: Follow the instructions to go through the simulation. Respond to the questions andprompts in the orange boxes.Note to teachers and students: TheFast Plants®Gizmo was created in collaboration with Wisconsin FastPlants. TheFast Plants 2 – Mystery Parentlesson was designed as a follow-up to theFast Plants 1 – Growthand Geneticslesson.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 purple stems, andanlis the recessive allelefor non-purple (green) stems.Clickon the image, clickEditandcomplete the Punnett square.1.TwoANL/anlplants are crossed. What percentage of the offspringplants will have purple stems?
2.AnANL/anlplant is crossed with ananl/anlplant. What is thepercentage of purple-stem offspring now?
Gizmo Warm-upIt is intern Mark’s first day at the Fast Plants laboratory, and he is eager toimpress. He gathers pollen from a set of plants on one side of the room andcarefully pollinates a set of plants on the other side. Then he goes out tolunch. When he returns, his supervisor Pam compliments Mark on the greatjob he did pollinating the flowers. “So, where did the pollen come from?” Markscratches his head in confusion. He knows it came from somewhere overthere, but which plants? He has no idea. “No problem,” says Pam. “We canfigure it out from the offspring.”In theFast Plants 2 – Mystery ParentGizmo, you will use genetics to determinethe identity of the unknown parent plant. To begin, select theMystery parentmode. Drag seed packetP1, the “mother” plants, to container 1 andF1, theoffspring plants, to container 2. ClickPlay(), and thenPause() after 10 simulated days.What are the traits of the P1 and F1 plants?

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®. 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.
