Student Exploration: Mouse Genetics (One Trait) Vocabulary: allele, DNA, dominant allele, gene, genotype, heredity, heterozygous, homozygous, hybrid, inheritance, phenotype, Punnett square, recessi... ve allele, traits 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? 2. How do they differ from one another? 3. What do you think their parents looked like? 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? 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? 3. Do you think mouse offspring will always look like their parents? Explain. All the offspring were white. Have a white belly, have spots of color throughout their body. They each have a different skin color and body mass. Yes, Because the genes from their parents pass on to the children, so the children will look like their parents. [Show More]
