The ability to digest lactose is controlled by

Question

Quizplus · Accepted Answer

The ability to digest lactose is primarily controlled by a single gene, called LCT, located on chromosome 2. This gene codes for the production of lactase, the enzyme necessary to digest lactose. Variations in this gene can cause lactase persistence (the ability to digest lactose into adulthood) or lactase non-persistence (the inability to digest lactose after weaning). Thus, variation at a single locus controls the ability to digest lactose.
