Understanding the Mouse Genetics: Two Traits Gizmo
What is the Mouse Genetics: Two Traits Gizmo?
The Gizmo is an interactive simulation designed by ExploreLearning that allows students to investigate inheritance patterns in mice. It demonstrates how two traits—such as fur color and ear shape—are inherited through genetic crosses. Students can select parent mice with specific traits, observe offspring phenotypes and genotypes, and analyze probability outcomes based on Mendelian genetics principles.
This virtual activity emphasizes key concepts such as:
- Dominant and recessive alleles
- Punnett square calculations
- Genotype and phenotype ratios
- Probability in genetic inheritance
