User talk:Carla R2D2/Genetic variation

Carla R2D2 (talk) 01:26, 18 November 2020 (UTC) Finished all the ideas I had to improve the article. If there are more to add please don't hesitate and continue making this article great. It is so important to know more about genetics and genetic variations.[reply]

Darwin’s theory of the mechanism of evolution begins with the variation that exists among organisms within a species. Individuals of one generation are qualitatively different from one another. Evolution of the species as a whole results from the differential rates of survival and reproduction of the various types, so the relative frequencies of the types change over time. Evolution, in this view, is a sorting process. For Darwin, evolution of the group resulted from the differential survival and reproduction of individual variants already existing in the group—variants arising in a way unrelated to the environment but whose survival and reproduction do depend on the environment. https://www.ncbi.nlm.nih.gov/books/NBK21378/#:~:text=Darwin's%20theory%20of%20the%20mechanism,among%20organisms%20within%20a%20species.&text=Evolution%20of%20the%20species%20as,the%20types%20change%20over%20time. - DONE Add in the contents the history to introduce Darwin's research. - DONE

In this article add...genetic variations, their mechanism, prevalence, biological impact,.. - DONE

Add and search more information and sources for Measurement, forms, maintenance and variability between populations. -DONE

It needs plenty of new photos, citations from reliable sources, adding to the table of contents, add more information, versality, improve grammar ... DONE

If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection). https://ghr.nlm.nih.gov/primer/mutationsanddisorders/evolution DONE

Random mutations are the ultimate source of genetic variation. Mutations are likely to be rare and most mutations are neutral or deleterious, but in some instances, the new alleles can be favored by natural selection https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2871826/ DONE

REVIEW

Did you write in your own words? Check that the article doesn’t contain excessive quotations, or copy any sources, even if you’ve given them credit.

Is the article clear to a non-expert? Check that you’ve explained acronyms and jargon in simple English the first time you use them.

Does the article let the reader decide for themselves? Rewrite any persuasive language that aims to sway a reader to a conclusion. Don’t ask the reader to do something. Let the reader make their own conclusions based on the facts.
