Quizplus · Accepted Answer

Fragile X syndrome is a genetic disorder caused by a mutation on the X chromosome. Since males only have one X chromosome, they are more likely to be affected by the disorder than females who have two X chromosomes. Fetal alcohol syndrome, autism, and Down syndrome are also genetic disorders, but they are not necessarily more likely to occur in males than females.
