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.
