Gizmo-Mouse_Genetics_2_Traits

Document Content and Description Below

Vocabulary: allele, genotype, phenotype, probability, Punnett square [Note to teachers and students: This Gizmo was designed as a follow-up to the Mouse Genetics (One Trait) Gizmo™. We recommend d... oing that activity before trying this one.] Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A single coin is flipped four times. What do you think is the most likely outcome? A. Four heads B. Three heads, one tail C. Two heads, two tails D. One head, three tails E. Four tails F. All are equally likely C: Two heads, two tails 2. What do you think are the odds of getting four tails in a row? Explain your answer. 1/16 Gizmo Warm-up On the Mouse Genetics (Two Traits) Gizmo, drag mice into the Parent 1 and Parent 2 spaces, and then click Breed to see their offspring. Experiment with different combinations of parent mice. 1. What must be true to have offspring with black fur? At least one parent has black fur. 2. What must be true to have offspring with white fur? iIf both parents are homozygous, then both parents must have white fur. White fur could also result if one or both parents are heterozygous for fur color. 3. What must be true to have offspring with black eyes? At least one parent has black eyes. 4. What must be true to have offspring with red eyes? One Parent 5. What must be true to have offspring with red eyes and white fur? If both parents are homozygous for these traits, then both parents must have red eyes and white fur. These traits could also result if one or both parents are heterozygous for fur color and eye color. This study source was downloaded by 100000824524045 from CourseHero.co [Show More]
