| 1. | Lactase tablets taken with any food containing lactose may also help.
|
| 2. | Lactase is encoded by a single genetic locus on chromosome 2.
|
| 3. | Scientists already knew that the lactase gene itself wasn't responsible.
|
| 4. | Food intolerance and lactase deficiency may also be confused with food allergies.
|
| 5. | :Lactase is to some extent inducible, and depends on environment.
|
| 6. | But at some time during childhood, lactase production slackens in most people.
|
| 7. | Lactase persistence is an example of such recent evolution.
|
| 8. | Lactase is present predominantly along the brush border villi of the small intestine.
|
| 9. | A at position-22018, have been independently linked to lactase persistence.
|
| 10. | Lactase-persistent alleles vary in their geographic distributions.
