Lactose Intolerance Inheritance and Variation of Traits Lab Kit

The Innovating Science Lactose Intolerance: Inheritance and Variation of Traits Kit is a three-part laboratory activity that explores the genetic basis of lactose intolerance, a recessive genetic trait. The kit includes all necessary materials for students to investigate genetic variation, inheritance patterns across generations, and the role of DNA and proteins in trait expression. This hands-on kit is designed for classroom use with enough materials for 15 groups of students. The three activities guide students through understanding how lactose tolerance develops, how DNA directs protein expression related to lactose intolerance, and how inheritance functions within populations. It provides a practical framework for studying genetics and evolution concepts through the lens of a relatable, real-world trait.
