Although this disorder was described in 1938, it was not until 1959 that the engine room was available to determine the cause of this disorder. Humans usually impart a score of 46 chromosomes (which be tiny, deoxyribonucleic acid-containing elements) that ar present in every booth of the body. DNA encodes genes, which specify all the proteins that make up the body and control its functions. there argon 23 matched cope withs of chromosomes in every booth. Each cell contains 22 pairs of chromosomes called autosomes that are the homogeneous in males and females. The remaining pair of chromosomes, the X- and Y- chromosomes, are not regulate similarly, and thus are not matched in the same flair as the autosomes. The X- and Y- chromosomes are called sex chromosomes. They are responsible for the disagreement in reading between males and females. A Y-chromosome contains genes responsible for testis branch; and the presence of an X-chromosome paired with a Y-chromosome forget determine male development. A female with formula transmittable defend has two X-chromosomes in each of her cells, 1 which she certain from her father and one, which she received from her mother.
cardinal X- chromosomes are required for normal ovarian development in females The female with Turners syndrome has only one X- chromosome in each of her cells receivable to a nondisjunction event during meiosis of her parents gametes. A careful examination of the transmitted material, usually by bureau of a blood sample, can confirm the diagnosis of Turners Syndrome. Depending on the item of nondisjunction of her parents gametes, the genotype of Turner Syndrome can vary. The majority of...
