The X chromosome carries traits that determine characteristics and conditions that may be passed down to the offspring. Some conditions carried on the X chromosome are hemophilia, Duchenne muscular dystrophy, fragile-x syndrome and red-green color blindness.
hair color, eye color, skin color, and gender
X- linked traits can only be inherited through the x-chromosome, while other traits are inherited either by both the x and y chromosome or just the y-chromosome. Source: BSCS Biology: A Molecular Approach, Blue Version Ninth Edition
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
Female transmit 23 chromosomes to the offspring. She has that unique chromosome called as X chromosome. This is transmitted to the offspring. From male you get either X or Y chromosome. From XX chromosome you get female child. From XY chromosome you get male child.

Sex linked is general term both for X linked and Y linked traits . Traits present only on Y chromosomeare also called Hollandric .
Traits carried on the x chromosome are said to be sex-linked

Most commonly sex linked traits are on the X chromosome, but rarely they can occur on the Y chromosome.
X-linked traits are transferred from parents, or a parentto their offspring on the X Chromosome. That is the biggest difference--as opposed to being located on any chromosome, X-linked traits are only transferred on X Chromosomes. A common X-linked trait is actually colorblindness. Often, X-linked traits or disorders are recessive; since men have only one X chromosome (because they are XY), they are often more prone to X-linked disorders, whereas women, who have two X chromosomes, often become "carriers"--that is, they have one X chromosome with a certain trait, but the other X chromosome has a dominant trait that masks the manifestation of the other trait.
Because the Y chromosome is so small and has relatively few genes, most sex-linked traits are governed by genes of the X sex chromosome, and are therefore X-linked.
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
The DNA of the Y-chromosome is the DNA that is transmitted only from father to son. This is because women have two X-chromosomes, one of which is given to each child. But men have one X-chromosome and one Y-chromosome. So if a father gives a Y-chromosome to his child that child will be male, while only females receive the father's X-chromosome.

Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
The chromosome is usually refered to as the "sex" chromosome. Chromosome #23. Also refered to as 'X' and 'Y'. XX for female, XY for male.
