Pedigrees and the Inheritance of Lactose Intolerance
What, exactly, causes lactose intolerance? Scholars view a video describing a Finnish study that determined why some people are tolerant while others are intolerant. They then use the data from the study to reenact the experiment and...

Got Lactase? The Co-Evolution of Genes and Culture
Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Regulation of the Lactase Gene
All human infants are lactose tolerant, yet some adults are lactose intolerant—why is that? Individuals discover the process of gene mutation through a study of the lactase gene (LCT). They understand the geographic connections,...
