Depending on the pattern of hair follicles, there is no X chromosome active in any skin cell. One of them carrying X chromosomes carries orange hair gem and other X chromosomes carry black hair gem. In the cells of the skin, the X-chromosomes carrying orange hair follicles are activated, where the hair is orange and the black hairs in the cells of which the X-chromosome carrying the fibers is activated, the hair is black in all places. Now we can uncover the secret of colorful identical twins. One of these X chromosomes result in mutation, due to the presence of eye-sensitized cell genes, Carries out the color blindness for the green light and the other X chromosomes contain the genes of normal light-sensitive cells. In the mother body of their mother, Jaidegote, it separates two separate embryos before the X-deactivation process. As a result, the two X-chromosomes present in each embryo cell carry a normal and other green colorful genes. Later, X-deactivation began separately in two embryos. The normal X chromosome inhibition of embryonic cells (X chromosomes active in green color) becomes a colorful bone that develops from the embryo. On the other hand, the X-chromosomes carrying the green color blindness in the embryonic cell (normal X chromosome activated) become a normal bone that develops from the embryo.
