      This genetic diversity has been shaped by factors such as geographic isolation, natural selection, and genetic drift. As a result, different populations may exhibit variations in traits such as skin color, immune response, and metabolism.
      One example of this genetic diversity can be seen in the ability to digest lactose. Many populations around the world have evolved the ability to digest lactose into adulthood, allowing them to consume dairy products. However, there are also populations, such as those in East Asia and parts of Africa, where the ability to digest lactose is less common.
      Another example of genetic diversity can be seen in the distribution of the sickle cell trait. Sickle cell anemia is a genetic disorder that affects hemoglobin, the molecule in red blood cells that carries oxygen. While having two copies of the sickle cell gene can lead to sickle cell disease, having only one copy of the gene provides protection against malaria. As a result, the sickle cell trait is more prevalent in regions where malaria is endemic.
      Overall, genetic diversity in human populations is a reflection of our evolutionary history and the diverse environments in which our ancestors lived. Studying this diversity can help us better understand the genetic basis of disease, as well as the ways in which humans have adapted to different environments over time.

    Mutations include mind control, the extension of claws, ice creation, manipulating metal, changing form, controlling the weather, firing energy beams with your eyes, traveling at supersonic speeds, able to tell which movie I'm referring to, and multiplying yourself.

    Great question. All life is connected back to the first life forms through our genetic material. Therefore the entire diversity of life on our planet was created through mutation (and genetic recombination).
    However if you are looking for simple "good" mutations in humans here is a start: lactose persistence, malaria resistance, the ccr5-Δ32 mutation that gives HIV-1 resistance, and my personal favorite tetrachromatic vision.

      How do you go from a 70% to a 105%? 105% implies that you got everything right along with extra marks, something that is impossible with the fact that you stated you only got 70% prior?

      You noticed the changes were bad. Changes are almost always neutral or bad, as far as the composition of the cookies, or cells.
      Plus the cookies were designed. They didn't, nor could come about by mindless chance.

      1. Poor diet: Eating a diet high in processed foods, sugar, and unhealthy fats can weaken genes and make the body more susceptible to illness. Consuming a diet rich in fruits, vegetables, whole grains, and lean proteins can help strengthen genes and improve overall health.
      2. Lack of physical activity: Leading a sedentary lifestyle can weaken genes and increase the risk of developing chronic diseases and infections. Regular exercise can help improve gene health and boost the immune system.
      3. Smoking and excessive alcohol consumption: Smoking and excessive alcohol intake have been linked to weakened genes and an increased susceptibility to disease. Quitting smoking and moderating alcohol consumption can help strengthen genes and improve overall health.
      4. Stress: Chronic stress can weaken genes and suppress the immune system, making the body more vulnerable to illness. Finding healthy ways to manage stress, such as practicing relaxation techniques, mindfulness, or engaging in regular physical activity, can help improve gene health and boost immunity.
      To become more immune to sickness, it is important to focus on strengthening genes through healthy lifestyle choices. This includes:
      1. Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins to provide essential nutrients that support gene health and immune function.
      2. Engaging in regular physical activity to improve gene health, boost immunity, and reduce the risk of chronic diseases.
      3. Getting enough sleep to allow the body to rest and repair, which is crucial for gene health and immune function.
      4. Managing stress through relaxation techniques, mindfulness, and other stress-reducing activities to support gene health and immune function.
      5. Avoiding smoking and excessive alcohol consumption, which can weaken genes and impair immune function.
      By making these lifestyle choices, individuals can strengthen their genes and improve their immune system, making them more resilient to sickness.

      Hey guys, did you know that the Nazis were all about that racial purity stuff? 🤢 They thought the Aryan race was superior and didn't want white people mixing genes with other races. But turns out, that kind of inbreeding can cause some serious genetic issues. 🧬 So white peeps, make sure to mix it up and keep that gene pool diverse! #GeneticDiversityRocks #SayNoToInbreeding #DiversityIsStrength 💪🏽 #NazisGotItWrong 🚫 #EmbraceTheMix 🌈 #ScienceRules 🧪🔬 #LoveHasNoRace ❤🧡💛💚💙💜

      @JoshNpublicgplus 10 лет назад

      Unless it's an insertion or deletion of three nucleotides, or a multiple of three nucleotides (6, 9, 24, etc.). Then, it's a non-frameshift mutation, and the rest of the amino-acids will be made.

    Info is great! But can you list all the mutations from the most harmful to the least harmful?

    can you make videos on the DNA repair system?

    Less information will NEVER become more information by distortion. A fixed set of information will never increase by distortion ( mutation ). Example: A copy machine will ALWAYS give you the SAME or LESS quality, never increase quality. In essence, evolution is the "perpetual motion" of biology. Mutation cripples, never creates!

      Copying machines don’t rearrange pages or page structures like mutations rearing genetic letters, bad analogy. If I have APHT and I change that to APHTA did I not add and get more?

      Compu Pawn most mutations are neutral and some are good so no mutations do not always cripple usually they do nothing. Distorting the code in such a way adds to the genetic code, if you have more after a mutation well then guess what that means something was added just because it’s a copy of an already existing letter is irrelevant.

    Most species (indeed most animals) have died before they ever got a chance to evolve. only a tiny percentage of the species to ever have existed are alive today. However life produces organisms in such abundance and these organisms reproduce in such vast numbers, that this is sufficient to ensure that those few non-harmful/beneficial mutations are carried forward.
