An X-linked recessive trait is coded for by a gene on the X-chromosome and is not dominant (is canceled out by the presence of a different allele).
Example of X-linked recessive traits are; Haemophilia A & B and Duchenne muscular dystrophy.

How does the inheritance of x-linked traits differ from that of other traits?
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
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.
X-linked traits carried by father will be passed on to who?
X-linked traits carried by the father will be passed on to his daughters. Sons will inherit their X chromosome from their mother and their Y chromosome from their father, so they will not inherit X-linked traits from their father.
What are six-linked traits?
Six-linked traits refer to genetic traits that are associated with genes located on the X chromosome. Because males have one X and one Y chromosome, they are more likely to express X-linked recessive traits, while females, having two X chromosomes, can be carriers without showing symptoms. Examples of such traits include color blindness and hemophilia. These traits can exhibit different patterns of inheritance and expression based on the sex of the individual.
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.
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.
How x linked traits affect the inheritance of sex linked traits?
Females have 2 X chromosomes so the X-linked genes follow the same rules of dominance & recessivity as the genes on the autosomes.
How does the inheritence of X linked traits differ from that of other traits?
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.

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.
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.
Which gender has a higher frequency of sex linked traits?
Males typically have a higher frequency of sex-linked traits because they have only one X chromosome, making recessive sex-linked traits more likely to be expressed. Females have two X chromosomes and can be carriers of recessive sex-linked traits without showing the phenotype.
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 the inheritance patterns of traits that are sex-linked?
Sex-linked traits are inherited through genes located on the sex chromosomes, typically the X or Y chromosomes. In humans, traits on the X chromosome are considered sex-linked, as males have only one X chromosome while females have two. This means that males are more likely to inherit sex-linked traits from their mothers, as they receive their X chromosome from their mother. In contrast, females have two X chromosomes, so they are less likely to show sex-linked traits unless both X chromosomes carry the same gene mutation.
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.
X-linked traits carried by father will be passed on to who?
X-linked traits carried by the father will be passed on to his daughters. Sons will inherit their X chromosome from their mother and their Y chromosome from their father, so they will not inherit X-linked traits from their father.
