What else can I help you with?
People with what ethnic breakdown usually do not become lactose intolerant?
Descendants of Northern Europeans and some Mediterranean peoples usually do not develop the condition.
Where did lactose tolerance probably first originate?
Nort
In what part of the world did the mutation for lactose tolerance first appear?
The mutation for lactose tolerance first appeared in ancient populations of Europe, specifically among early farmers from the region that is now modern-day Turkey. This mutation allowed individuals to digest lactose, the sugar found in milk, beyond childhood.
Where and when did lactose tolerance first develop?
Lactose tolerance first developed in human populations in regions where dairy farming became prevalent, particularly in northern and central Europe around 5,000 to 7,000 years ago. This adaptation allowed individuals to digest lactose, the sugar found in milk, beyond infancy. The ability to consume milk from domesticated animals provided a nutritional advantage, promoting the spread of lactase persistence in these populations.
What are some example of helpful desirable mutation?
Lactose tolerance
What is lactate tolerance?
Lactose intolerance is the inability to metabolize lactose, because of a lack of the required enzyme lactase in the digestive system.
What are good status on facebook?

What percentage of the adult population shows good tolerance to lactose indigestion?
30%
A mutation in what results in lactose tolerance?
A mutation in the LCT gene, which is responsible for producing the lactase enzyme, results in lactose tolerance. This mutation allows individuals to continue producing lactase into adulthood, enabling them to digest lactose, the sugar found in dairy products.
Why is lactose tolerance also called lactase persistence?
Lactose tolerance is referred to as lactase persistence because it describes the continued production of lactase, the enzyme that breaks down lactose, into adulthood. In many mammals, lactase production decreases after weaning, leading to lactose intolerance. However, in certain human populations, genetic adaptations allow for sustained lactase production, enabling these individuals to digest lactose throughout their lives. This genetic trait is termed lactase persistence, highlighting the ongoing ability to process lactose effectively.
How can you determine if your child is lactose intolerant?
To determine if your child is lactose intolerant, you can observe symptoms such as bloating, gas, diarrhea, or stomach cramps after consuming dairy products. You can also consult a healthcare provider for tests like a lactose intolerance breath test or a lactose tolerance test.
