About inheritance and genetics:
Inheritance of Lactose Intolerance refers to whether the condition is inherited
from your parents or "runs" in families.
The level of inheritance of a condition depends
on how important genetics are to the disease.
Strongly genetic diseases are usually inherited,
partially genetic diseases are sometimes inherited,
and non-genetic diseases are not inherited.
