Usage


In news:

This happens because intestinal production of the enzyme lactase declines with age in all but a small segment of the world's population.

If you're lactose intolerant, you may have better luck with raw milk since its bacteria creates an enzyme called lactase that breaks down lactose.
Those with the GG genotype are known as lactase non-persistent (aka likely, though not necessarily, lactose intolerant ).

In science:

Using this method, Voight and colleagues find strong evidence for recent selection among Europeans in the lactase gene LCT, which is important for metabolism of lactose beyond early childhood.
The transmission sense of information
The favored allele results from a single nucleotide change 14 kb upstream of the lactase gene on the nearly 1 Mb haplotype.
The transmission sense of information
Positive selection has presumably occurred because the ability to process lactase throughout life became advantageous with the invention of animal agriculture approximately 10,000 years ago.
