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.

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.
Why Neandertals were able to tolerate milk as adults?
Neandertals, like modern humans, likely developed lactase persistence, allowing them to digest lactose in milk as adults. This adaptation is thought to have emerged independently in multiple populations as a result of the domestication of animals for dairy farming. This genetic mutation provided a nutritional advantage by allowing individuals to consume a nutrient-rich food source year-round.
What is The inability for the body to process dairy products is?
The inability for the body to process dairy products is known as lactose intolerance. This condition occurs when the small intestine doesn't produce enough of the enzyme lactase, which is needed to digest lactose, the sugar found in milk and dairy products. Symptoms may include bloating, gas, diarrhea, and stomach cramps after consuming dairy.
What is the tolerance level of noise for human beings?
The tolerance level of noise for human beings varies depending on the individual and the context. Generally, exposure to noise levels above 85 decibels for extended periods can cause hearing damage. It is important to limit exposure to loud noise to protect hearing health.
What are the four forces of human evolution?
The four forces of human evolution are mutation, genetic drift, gene flow, and natural selection. Mutation introduces new genetic variations, genetic drift refers to random changes in gene frequencies within a population, gene flow involves the transfer of genetic material between populations, and natural selection is the process by which certain traits become more common in a population due to their advantage for survival and reproduction.
What are some example of helpful desirable mutation?
Lactose tolerance
Why did the lactose tolerance mutation in the east African herders spread so rapidly with in population?
It was a selective advantage for survival during droughts.
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 did lactose tolerance probably first originate?
Nort
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.
A mutation that results in the death of the organism is a?
lethal mutation
What are good status on facebook?
_____________ is having zero tolerance for the lactose intolerant
A mutation that results in the death of the individual is called?
A deleterious mutation.
What is lactose and tolerance?
cant have any dairy like milk and cheese or anything on it
What percentage of the adult population shows good tolerance to lactose indigestion?
30%
Will a point mutation cause the cell to make an incomplete polypeptide if the mutation results in a stop codon?
Yes, a point mutation will cause the cell to make an incompelete polypeptide chain that is non-functional, if the mutation results in a stop codon. This type of a mutation is also called as the Nonsense Mutation.
How does culture evolution affect development?
Culture evolution can influence development by shaping beliefs, values, and norms that guide individuals' behavior and decision-making. As culture evolves, new ideas and practices may emerge that either support or hinder development, depending on how they align with individuals' needs and goals. Additionally, cultural evolution can impact access to opportunities, resources, and social structures that can either foster or impede development outcomes.
