  2. Human skin color - Wikipedia

    en.wikipedia.org/wiki/Human_skin_color

    Human skin color ranges from the darkest brown to the lightest hues. Differences in skin color among individuals is caused by variation in pigmentation, which is the result of genetics (inherited from one's biological parents ), exposure to the sun, disorders, or some combination thereof. Differences across populations evolved through natural ...

    Haemophilia figured prominently in the history of European royalty in the 19th and 20th centuries. Queen Victoria and her husband, Prince Albert, of the United Kingdom, through two of their five daughters – Princess Alice and Princess Beatrice – passed the mutation to various royal houses across the continent, including the royal families ...

    It can be prevented if one parent has normal genes, giving rise to screenings that empower carriers to select partners with normal hemoglobin. A study aimed at detecting the genes that could give rise to offspring with sickle cell disease. Patients diagnosed with beta thalassemia have MCH ≤ 26 pg and an RDW < 19.

  5. Sickle cell-beta thalassemia - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell-beta_thalassemia

    Sickle cell-beta thalassemia is caused by inheritance of a sickle cell allele from one parent and a beta thalassemia allele from the other. Mutations. A sickle allele is always the same mutation of the beta-globin gene (glutamic acid to valine at amino acid six). In contrast, beta-thalassemia alleles can be created by many different mutations ...

    Haplogroup E-M2, also known as E1b1a1-M2, is a human Y-chromosome DNA haplogroup.E-M2 is primarily distributed within Africa followed by West Asia. More specifically, E-M2 is the predominant subclade in West Africa, Central Africa, Southern Africa, and the region of the African Great Lakes; it also occurs at moderate frequencies in North Africa, and the Middle East.

  9. Duffy antigen system - Wikipedia

    en.wikipedia.org/wiki/Duffy_antigen_system

    The Duffy antigen/chemokine receptor gene (gp-Fy; CD234) is located on the long arm of chromosome 1 (1.q22-1.q23) and was cloned in 1993. The gene was first localised to chromosome 1 in 1968, and was the first blood system antigen to be localised. It is a single copy gene spanning over 1500 bases and is in two exons.
