It is a character which comes from alleles on the X chromosome. Generally recessive. In females, it takes two of these recessive alleles to be expressed.
But in males, the y chromosome is so small that there is often no corresponding allele on the y chromosome. So a single recessive allele will be expressed.
A classic example is hemophilia. For a female to have hemophilia, she has to have two alleles for the disorder. For a male it only takes one. This is why there are so many more males who are hemophiliacs than females who are hemophiliacs.

s*x-linked character, an observable feature of an organism controlled by the genes on the chromosomes that determine the organism’s s*x. Each individual has a pair of s*x chromosomes; one member of the pair is inherited from each parent.
