Who gets FG Syndrome and why?
"FG Syndrome is inherited as an X-linked recessive trait. Human traits, including the classic hereditary diseases, are the product of the interaction of two genes, one received from the father and one from the mother. X-linked recessive disorders are conditions that are coded on the X chromosome. Females have two X chromosomes, but males have one X chromosome and one Y chromosome. Therefore, in females, disease traits on the X chromosome can be masked by the normal gene on the other X chromosome. Since males only have one X chromosome, if they inherit a gene for a disease present on the X, it will be expressed. Men with X-linked disorders transmit the gene to all their daughters, who are carriers, but never to their sons. Women who are carriers of an X-linked disorder have a 50% risk of transmitting the carrier condition to their daughters, and a 50 percent risk of transmitting the disease to their sons."
