About this item
Lactose intolerance is common, but is actually a recessive genetic trait! Humans and other mammals are only meant to drink milk as infants and as they grow, they lose the ability to digest lactose. As populations began to develop, the domestication of cows and drinking milk into adulthood became more common, leading to a tolerance for lactose. Learn about variation, inheritance, and the role of DNA and proteins in expression of traits in this three-part laboratory activity.
