Document Content and Description Below

Vocabulary: allele, DNA, dominant allele, gene, genotype, heredity, heterozygous, homozygous, hybrid, inheritance, phenotype, Punnett square, recessive allele, trait Prior Knowledge Questions (Do th... ese BEFORE using the Gizmo.) 1. The image shows a single litter of kittens. How are they similar to one another? _They are the same species. Some have black spots, while others have orange 2. How do they differ from one another? and brown spots. 3. What do you think their parents looked like? They probably also had brown/black, orange spots on their bodies. 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 several times. What do the offspring look like? Their offspring will have a black coat of fur covering their bodies. 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? Yes Explain: Since both parents have the same fur coat color, there is a high probability _ This study source was downloaded by 100000824524045 from CourseHero.com on 04-25-2021 17:29:51 GMT -05:00 https://www.coursehero.com/file/82311656/Gizmo-Mouse-Genetics-1-Traitdocx/ This study resource was shared via CourseHero.com that their offsprings will also adopt the same fur color.

Question: What patterns are shown by offspring traits? 1. Predict: What do you think the offspring of a black mouse and a white mouse will look like? Black 2. Observe: Click Breed several times. What do you see? _ The offspring are all black. 3. Observe: Drag two offspring into the Holding Cages. These mice are called hybrids because their parents had different traits. Click Clear, and then breed the two hybrids. What do you see now? The majority of the offsprings a [Show More]
