Genetic variations are the differences in individuals within a population. Variations are the visual differences everyone has caused by random changes in our DNA. Mutations are the most primary source of variation that happens in every type of life form. Mutations are very common and happen all the time. They are mistakes that occur during the process of replicating the DNA. Mutations include skipping, inserting, deleting, duplicating, copying incorrectly, or moving huge chunks of DNA. Mutations that occur during fertilization are passed down to the offspring. They occur at random and can change the function of a protein. A mutation that has happened to humans is that we have different colored skin. We came from our ancient African ancestors, as they migrated humans evolved. Natured helped us mutate and get lighter skin to help us survive with the amount of light there was in our environment. There are many disadvantages and advantages to genetic mutations.
It is when our genes are shuffled during reproduction and creates new gene combinations. Recombination happens during egg and sperm production. It also happens in organisms that reproduce asexually. Variation is important because it helps the human race evolve over time. Humans were not able to digest milk, but as time went on, humans evolves and were able to digest milk even until they were older and as adults. In conclusion, variation is a positive advantage to the human race because every variation that happens is passed down to other generations so they can live and survive in their environment. Variation helps us adjust to our environment as we grow and evolve over

    Evolution is the process by which organisms develop unique derived traits. Evolved traits that decrease an organism’s survival rate are selected against in a population. Traits that increase an organism’s survival rate, on the other hand, are often selected for, meaning that those traits will appear more frequently in the genetic codes of members in a population. This process of selection can take several forms, one of them called sexual selection. Sexual selection occurs when one member of a particular species selects a mate with more favorable traits than other members of their species. An example of sexual selection would be the evolution of “hairlessness” in modern humans. Modern humans do not have a single coat of undiversified hair, unlike

    Evolution is described, as being the change that occurs on a genetic level when a new generation spouts from an ancestral population. Change is destined to happen. That is why in the science of biology the word evolution means descent with modification. Through various factors such as the temperature of the environment, humidity, and altitude a species will adapt to survive and will eventually pass on genetic traits that help the species next generation survive.

    The study of heredity is what is referred to as genetics. Genetic diversity is therefore described as any variation in the genes, chromosomes, nucleotides or sometime change in the whole genomes of an organism. Though genome is not well branded term for many, it is the entire balance of DNA within the cell or organelles of the organism. When one talks of genetic diversity in its most elementary level, it is represented by differentiation in the sequence of nucleotides that form the DNA within the cell of an organism.

  • Evolution: Mutation, Natural Selection, Genetic Drift and Gene Flow

    758 Words  | 2 Pages

    Mutation happens when the DNA gene gets changed, moves, or is damaged. When this happens it causes the genetic message to be carried by that gene to be different. This process can occur in somatic cells. The somatic cells are all the cells that are a living organism except the reproductive cells, meaning the body. For example, the skin cells on your legs are and will not be passed on to ones offsprings. In addition those leg cells will not effect the evolution. Another occurrence is called gametic mutations, which is in a woman's eggs and or in a man's sperm. These are cells that are and can be passed on to ones offsprings, and they are the essentials for the evolution. There are three effects mutation causes to a species. Species can only takes on one of the three. The three effects are bad, neutral, and good. Having a bad mutation can cause one to have a harder time being able to survive. Having a neutral mutation will not change or help one to survive. Having a good mutation will help one to survive and have a better chance of survival. However, mutation is random in the evolution, and provides raw material for natural selection, genetic drift, and gene flow...

  • The Pros And Cons Of Natural Selection

    1633 Words  | 4 Pages

    Natural selection is simple yet complex process that allows species adapt to its environment. Natural selection guides evolution by “sifting out” favorable traits that increase survival for the species. Natural selection is driven by reproductive success. If a species can reproduce and its offspring survive than any traits in its genotype that assisted in its survival will be passed on from generation to generation and ensure that the species will live on. Around the time the Theory of Evolution was suggested, society was very religious and very pressed on the Theory of Creation, so the publication of Darwin’s The Origin of Species by Means of Natural Selection caused a lot of controversy. Darwin gave the world strong evidence that natural selection and evolution played a major role in the development of the species that we see today. Of course natural selection is not the only process driving evolution. In order for natural selection to happen, the species has to have genetic variation. Genetic variation happens because of mutations and recombination of genes. Other processes that contribute are gene flow and genetic

    A lot of conflicts, debates, and even fights are about a theory by a scientist called Charles Darwin. This theory is the theory of evolution, which is viewed as the most important and the most debated theory of all-time. This theory changed science forever. However, this theory is not believed by everyone and some people even say that Charles Darwin, who formulated this theory, even said it was wrong before he died. However, this theory is not all wrong and useless, because natural selection, which is the mechanism of this theory, is believed in by most people and scientist. Although natural selection is believed in by most people and scientist, there is an argument that natural selection is a random process, however natural selection is definitely not a random process.

    The DNA code, that forms our genes, was the missing key for Darwin to understand how things evolved. DNA does not stay the same, it can be changed by mutations. Mutations are needed to generate variations. Without the mutations things would stay the same generation after generation. Pieces of DNA called a switch can turn certain genes on or off. Genetic Switches helps to create mutations which are sometimes responsible for an entire new species spawning from another. This is how a snake can evolve from a four legged animal, and how a whale 's front flippers has bones inside that resembles

    ...generations. If it is a beneficial mutation, then it will likely not only pass on through reproduction, but those offspring will have better odds of reproducing in order to “spread” that trait onto future offspring. This is the process of natural selection. If there are enough changes or the change is drastic enough, a new species can evolve. So, evolution comes about as a result of changes to DNA and some of those changes to DNA can come from external factors such as environment, climate, and culture.

  • genetic mutations

    1467 Words  | 3 Pages

    A genetic mutation is a permanent change in the sequence of the DNA that makes up a gene. A mutation of these sorts can be caused by either inheritance from the parent or caused sometime during the life of someone. The mutation that has been inherited is called a germline mutation. Germline mutations affect virtually the entire body, and they seem to be present in every cell. A somatic mutation, or one that is caused in the DNA of a single cell sometime during the life, can be caused by an environmental factor or a wrong bonding in the DNA molecule. These cannot be passed down to the next generation of children because they occur in a specific cell as opposed to in a reproductive cell. Some mutations occur in the embryo as it is growing. These may occur during cell division, and some of the cells may or may not inherit this mutation. Some mutations are extremely rare, and others are incredibly common. Those that occur in more than one percent across a population are considered polymorphisms. Polymorphisms are considered normal variations in DNA, and they are known to cause simple changes such as variations in blood types and hair color. Although these are not typically fatal, they can influence the creation of some disorders (Lister Hill National Center for Biomedical Communications, U.S. National Library of Medicine, National Institutes of Health, Department of Health and Human Services, USA.gov, 2013).

  • The Pros And Cons Of Genetic Engineering

    925 Words  | 2 Pages

    Scientists and the general population favor genetic engineering because of the effects it has for the future generation; the advanced technology has helped our society to freely perform any improvements. Genetic engineering is currently an effective yet dangerous way to make this statement tangible. Though it may sound easy and harmless to change one’s genetic code, the conflicts do not only involve the scientific possibilities but also the human morals and ethics. When the scientists first used mice to practice this experiment, they “improved learning and memory” but showed an “increased sensitivity to pain.” The experiment has proven that while the result are favorable, there is a low percentage of success rate. Therefore, scientists have concluded that the resources they currently own will not allow an approval from the society to continually code new genes. While coding a new set of genes for people may be a benefitting idea, some people oppose this idea.

Mutations are the origin of the source of genetic diversity (9).Mutation that are harmful, hinders the chances of the organism chances of survival and are likely to die along with the mutations. Beneficial mutations increase the chances of the individual to survive in its environment, and they will be more likely to reproduce and pass on the gene to future generations (9).
