Student Exploration: Mouse Genetics (One Trait) Vocabulary: allele, DNA, dominant allele, gene, genotype, heredity, heterozygous, homozygous, hybrid, inheritance, phenotype, Punnett square, recessiv... e allele, trait Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. The image shows a single litter of kittens. How are they similar to one another? Blue eyes, white sections, facial structure 2. How do they differ from one another? They all have different fur patterns and colors 3. What do you think their parents looked like? It is hard to decide because they all show such different colors and patterns, but one could be orange black and white, and the other could have a brown striping pattern Gizmo Warm-up Heredity is the passage of genetic information from parents to offspring. The rules of inheritance were discovered in the 19th century by Gregor Mendel. With the Mouse Genetics (One Trait) Gizmo™, you will study how one trait, or feature, is inherited. 1. Drag two black mice into the Parent 1 and Parent 2 boxes. Click Breed to view the five offspring of these parents. What do the offspring look like? black The appearance of each mouse is also called its phenotype. 2. Click Clear, and drag two white mice into the parent boxes. Click Breed several times. What is the phenotype of the offspring now? white 3. Do you think mouse offspring will always look like their parents? no Explain: sometimes the parent may carry a trait but not show it and they will pass it down, or there could be a mutation [Show More]
