Product Details

Students are intrigued to learn exactly why they often exhibit traits similar to their parents. By performing this straightforward mathematical and visual example, students are able to thoroughly grasp complex genetic concepts. This activity simulates eye color as it would be inherited through three generations assuming independent assortment of the genes and polygenic inheritance. Students complete a family pedigree featuring the number of dominant alleles each individual inherited from their parents. The dominant and recessive alleles are represented by two different colored bingo chips. The number of dominant alleles each person inherits is determined by the number of dominant alleles drawn from the paper bag containing the alleles of each parent. Watch the excitement build as students visualize the concrete differences in the number of dominant alleles inherited by recreating their pedigree by mixing using two different color solutions drop-wise in a reaction plate. Kit includes enough materials for 30 students working in pairs or 15 groups of students, reproducible student handouts and detailed Teacher Notes. 96-well reaction plates required but not included.

Performance Expectations

MS-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
HS-LS3-3. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.
