Gizmo Mouse Genetics (Two Traits) _2021 | 100 Percent Grade

Document Content and Description Below

Student Exploration: Mouse Genetics (Two Traits) Vocabulary: allele, genotype, phenotype, probability, Punnett square [Note to teachers and students: This Gizmo was designed as a follow-up to the Mo... use Genetics (One Trait) Gizmo™. We recommend doing 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 G. H. 2. What do you think are the odds of getting four tails in a row? Explain your answer. A. B. The odds of getting four tails in a row are ½ * ½ * ½ * ½ because every flip has an equal probability of being heads or tails. So with 4 flips you would have a 1/16 chance. C. D. E. Gizmo Warm-up F. 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. G. 1. What must be true to have offspring with black fur? H. I. Since black fur is dominant, the allele for black fur must be present. J. 2. What must be true to have offspring with white fur? Both alleles must code for white fur since it is a recessive trait. K. 3. What must be true to have offspring with black eyes? If the allele for black eyes is present, you will have them because it is a dominant trait. L. 4. What must be true to have offspring with red eyes? Both alleles must code for red. M. N. What must be true to have offspring with r [Show More]
