Modeling the Inheritance of Traits

Kit #912S
Modeling the Inheritance of Traits

Students model the diversity of offspring possible from two parents and discover patterns of inheritance other than strict dominant/recessive traits. These patterns help them model and explain the wide variation that can result from sexual reproduction and explore the cause-and-effect relationships for additional traits of the critters.
