2019 Name: Date: Student Exploration: Fast Plants ® 2 Mystery Parent Note to teachers and students: The Fast Plants ® Gizmo was created in collaboration with Wisconsin Fast Plants. The Fast Plants 2 Mystery Parent lesson was designed as a follow-up to the Fast Plants 1 Growth and Genetics lesson. Vocabulary: chi-squared test, degrees of freedom, deviation, dihybrid Punnett square, rosette-dwarf Prior Knowledge Questions (Do these BEFORE using the Gizmo.) In the Fast Plants 1 lesson you learned about two alleles for stem color. ANL is the dominant allele for purple stems, and anl is the recessive allele for non-purple (green) stems. 1. Two ANL / anl plants are crossed. What percentage of the offspring plants will have purple stems? 2. An ANL / anl plant is crossed with an anl / anl plant. What is the percentage of purple-stem offspring now? Gizmo Warm-up It is intern Mark’s first day at the Fast Plants laboratory, and he is eager to impress. He gathers pollen from a set of plants on one side of the room and carefully pollinates a set of plants on the other side. Then he goes out to lunch. When he returns, his supervisor 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 it came from somewhere over there, but which plants? He has no idea. “No problem,” says Pam. “We can figure it out from the offspring.” In the Fast Plants 2 Mystery Parent Gizmo, you will use genetics to determine the identity of the unknown parent plant. To begin, select the Mystery parent mode. Drag seed packet P1 , the “mother” plants, to container 1 and F1 , the offspring plants, to container 2. Click Play ( ), and then Pause ( ) after 10 simulated days. What are the traits of the P1 and F1 plants?
2019 Activity A: Creating a hypothesis Get the Gizmo ready: On the Mystery parent mode, click Reset ( ). Turn on Auto grow and Show hints . Introduction: In this lesson you will look at the stem color and leaf color of Fast Plants ® . Recall that the stem color is controlled by two alleles: ANL (purple) and anl (green). The leaf color is controlled by the alleles YGR (green) and ygr (yellow- green, which we will refer to as “yellow” ). The ANL and YGR alleles are dominant, while the anl and ygr alleles are recessive.
