User avatar Hi Ryu2c2000,

Most causes of mental retardation are ultimately unknown. In these cases it probably, emphasis on probably, isn't hereditary.

However, one of the more common known causes of mental retardation is a condition called fragile X syndrome. In this case, the condition is carried on the X chromosome. Because of this, boys who get the affected chromosome will have the syndrome and generally have some degree of mental retardation. Girls, who have 2 X chromosomes, may not show the deficit with only one affected chromosome. These girls are called carriers.

Carriers who have children will have a fifty/fifty chance of having affected boys.

There are some other hereditary syndromes that are not sex chromosome associated. These syndrome will vary in their odds of transmission.

I hope this helps some.

Best wishes.
