People of European descent may also lack certain genetic variations that are common in other populations, such as lactase persistence, which allows individuals to digest dairy products throughout their lifetime. This genetic variation is most common in people of European descent, but is less common in other populations, such as those of African or Asian descent. In addition, people of European descent may also have a higher prevalence of certain genetic diseases, such as cystic fibrosis or hemochromatosis. It is important to note that genetic variations exist in all populations and do not determine an individual's worth or abilities.
