Yes. It is found as a mutation on the X chromosome (a sex chromosome) so it is sex linked. The gene for Fragile X is carried on the X chromosome. Because both males (XY) and females (XX) have at least one X chromosome, both can pass on the mutated gene to their children.
No.
Three disorders which are sex-linked are: Fragile X syndrome Duchenne muscular dystrophy Colour blindness (most forms, but not all)
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.

No, fragile x syndrome is not progressive
Fragile X syndrome is caused by a mutation that prevents the Fragile X mental retardation (Fmr-1) gene from being transcribed. This gene is located on the X chromosome (the sex chromosome). Since males only carry one of these chromosomes, they are twice as likely to be affected by the mutation than females.
Turner's syndrome is a sex-linked monosomy. In this case, the person has only one X and no second X or Y.
Males and females can be carriers, male carriers can only pass on to their daughters, they will be carriers as well have a premutation. Females can pass on to their sons or daughters, they will have the premutation or the full mutation.
