The human genome is split into 23 pairs chromosomes (DNA), which atomic number 18 coiled in a spiral ladder event through nucleotide hydrogen bases (cytosine-c, guanine-g, thymine-t, adenine-a) (fig1 below). Human cells brook 46 chromosomes (fig 2 below) - 22 pairs of autosomes chromosomes 1 to 22 and two waken chromosomes X and y or X and X depending sex activity (sex-linked). Within these chromosomes are roughly 30,000 components that controls and construct the electric organs in the body. There are everywhere approximately 250 know sex-linked infirmitys, come toing every organ system. Of these, 95% affect males as it reflects the presence of the abnormal gene on the X chromosome, which is present in two copies in females and one in males. Males inherit the X chromosome from their grow and the Y chromosome from their father. Since this is the case, abnormalities on the X chromosome from the mother will usually unmistakable as a disorder within 50% of her males offsp rings. Since females have a chromosomal make-up of XX, inheriting an X chromosome with unsoundness variances in it mainly will not produce the disease condition. The healthy X chromosome that the female has inherited from her other raise male masks the pathological X chromosome. The female with one mutated X chromosome would be know as a mailman because she tummy pass the mutation onto her children, though she may not be directly preserve by it. An X-linked disease could affect a female, in a lower percentage, if her mother is a carrier and the disease affects her father. If her mother and her father are both affected with the disease, she will almost certainly be afflicted with the disease as well. disdain these many sex-linked diseases, at present antepartum diagnosis can specifically be made in fewer than 40 diseases. These sex-linked diseases of single... If you want to get a dear essay, order it on our website: OrderCustomPap! er.com
