The X chromosome is linked to the overwhelming majority of sex linked traits, except for one - gender.
Short Answer:
There are just over a thousand genes on the X chromosome and about 26 on the Y. Of the 26 on the Y, 9 relate to sperm and one (SRY) relates to male anatomy, the others involved in general tasks.
The fact that there are a hundred times more genes on the X chromosome means that traits related to the X, and variations in those traits, are far far more common.
Sex-linked traits are those that can only be passed along from the father and not the mother or from the mother and not the father.
Obviously, males do carry and pass on sex-linked traits, just not very many.
Gender can only be passed along from the father, along with genes related to sperm.
Females pass on to the male offspring a larger number of traits, (such as some color blindness and male pattern baldness) which have no counterpart in the Y chromosome.
More:
Males have an X and a Y chromosome and females have two X chromosomes.
Because the Y chromosome is smaller than the X with far fewer genes, there are genes carried only on the X and only gotten from the mother. That does not mean that all males have Y chromosomes that are the same.
Overwhelmingly though, the absence of the set of genes on the Y chromosome results in the corresponding genes on the X chromosome being expressed, in particular all of the X-linked disorders of a gene of an X chromosome in a male do not have a second X gene that can be expressed to compensate. Thus, there are a set of sex-linked traits that can only come from the mother.
(Color blindness and male pattern baldness are the two most discussed examples.)
A male offspring (son) has the same Y chromosome as the father and hence any traits influenced by that chromosome.
A female offspring (daughter) has the same X chromosome as the father and hence any traits influenced by that chromosome. A recessive gene on the X from the father will not usually be expressed in a daughter, but a dominant gene on the X from the father will be expressed in the daughter.
For a female to inherit a trait associated with an X-chromosome recessive gene, there must be two copies, one from each parent.
Aside:
The issue of gender-connected inherited traits has much more complexity than this simple discussion can address. For example, not all of the so-called male characteristics are carried on the male (Y) chromosome. The expression of genes on other chromosomes, from both the mother and father, is influenced by genes on the Y chromosome or simply by the absence of two X chromosomes. The reader should investigate further.
Caveat: This discussion applies to humans and other mammals with the XX/XY sex determination system. See related links.
Fun Fact: A woman discovered that the Y chromosome was male. While studying worms, in 1905, Nettie Stevens at Bryn Mawr College identified the Y chromosome as the determining factor in gender.

What is the term for traits that are carried on the sex chromosome?
The term for traits that are carried on the sex chromosomes is "sex-linked traits." These traits are often associated with genes located on the X or Y chromosome, and they can exhibit different inheritance patterns in males and females due to the presence of two X chromosomes in females and one X and one Y chromosome in males. An example of a sex-linked trait is color blindness, which is commonly linked to the X chromosome.
Which type of inheritance involves traits linked to a sex chromosome?
Sex-linked inheritance involves traits that are linked to genes on the sex chromosomes (X and Y). Traits carried on the X chromosome are typically expressed differently in males and females due to differences in the number of X chromosomes they inherit. Examples include color blindness and hemophilia.
What is a trait that is passed from parent to child on the X chromosome called?
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.
When are sex link traits due to occur?
Traits caused by proteins coded for on the sex (X and/or Y) chromosomes.
Sex-linked traits are caused by alleles on the?
Sex-linked traits are caused by alleles on the sex chromosomes, particularly the X chromosome in humans. These traits are often more commonly expressed in one sex over the other due to differences in sex chromosome inheritance.
Where are sex linked chromosomes most often carried?
In humans, most sex linked traits are carried on the X sex chromosome.
Sex-linked traits A.Can be carried on the Y chromosome B. Affect males and females equally C. Can be carried on chromosome 20 D.A and B E. None of the above?
D. A and B. Sex-linked traits are carried on the sex chromosomes, with traits on the Y chromosome affecting males only. Males are more likely to express recessive sex-linked traits due to having only one copy of the X chromosome.
Are all sex-linked traits located on the X chromosome?
No, not all sex-linked traits are located on the X chromosome. Some sex-linked traits can also be located on the Y chromosome.
Which type of inheritance involves traits linked to a sex chromosome?
Sex-linked inheritance involves traits that are linked to genes on the sex chromosomes (X and Y). Traits carried on the X chromosome are typically expressed differently in males and females due to differences in the number of X chromosomes they inherit. Examples include color blindness and hemophilia.
Where are sex linked traits found?
Most commonly sex linked traits are on the X chromosome, but rarely they can occur on the Y chromosome.
How are the alleles for sex-linked traits inherited?
Sex-linked traits are inherited through alleles located on the sex chromosomes, specifically the X and Y chromosomes. In humans, females have two X chromosomes (XX) and males have one X and one Y chromosome (XY). Since sex-linked traits are carried on the X chromosome, they are inherited differently in males and females. Males inherit sex-linked traits from their mothers, as they receive their only X chromosome from their mother. Females can inherit sex-linked traits from both parents, as they receive one X chromosome from each parent.
What are two sex-linked traits present in humans?
Two sex-linked traits present in humans are color blindness and hemophilia. These traits are carried on the X chromosome and are more commonly expressed in males due to their inheritance pattern.
Are sex linked traits also called X-linked traits?
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.
A trait controlled by a gene on the sex chromosome is know as a?
A trait controlled by a gene on the sex chromosome is known as a sex-linked trait. These traits are often inherited in a sex-specific manner, with different patterns of inheritance depending on whether the gene is located on the X or Y chromosome.
What are linked traits?
Normally sex-linked traits are carried only on the X chromosome, meaning a sex-linked gene can only be inherited from the father's X or the two mother's X's. However, there are occasions where the trait is carried down by the Y chromosome, meaning only the males would inherit it, and it would be expressed. This is very uncommon because the Y chromosome carries very little genetic material/information in comparison to the Y chromosome.
What is a trait that is passed from parent to child on the X chromosome called?
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.
What are the sex-linked traits in humans and how do they differ between males and females?
Sex-linked traits in humans are genetic characteristics that are carried on the sex chromosomes, X and Y. In males, who have one X and one Y chromosome, sex-linked traits are typically passed down from the mother on the X chromosome. In females, who have two X chromosomes, sex-linked traits can be passed down from both parents. This means that males are more likely to exhibit sex-linked traits if they inherit a recessive gene on their X chromosome, while females need to inherit two recessive genes, one from each parent, to show the trait.
