I think I read somewhere that there are some variants of it that are recessive and others that are dominant.

How do you know if a trait is sex linked dominant or sex linked recessive?
get a test
Is color blind dominant or recessive?
recessive
How do you express sex linked genes?
Let's take red-green color vision as an example. You could use the letter n to represent the dominant and recessive alleles. You could use a capital letter N to represent the normal allele, which is dominant, and a lowercase letter n to represent the defective allele, which is recessive. The genotypes for the sex-linked trait would be as follows: female, homozygous dominant: XNXN; female, heterozygous: XNXn; male dominant, XNY; male recessive, XnY.
If a daughter expresses an x-linked recessive gene she inherited the trait from?
For a female to express an X linked recessive gene, she must have inherited it from both parents. Every female (without disease) has two X chromosomes: XX, while males have an X and a Y: XY. A recessive gene is one that will not be expressed if there is a copy of the dominant gene present. sex linked genes have their own special set of rules because the sex chromosomes are the only ones which vary by presence or absence between different people. Because a male only has one X chromsome, he will express all the genes on that chromosome; this can be used to determine if a gene is sex linked and recessive/dominant. A recessive gene will not be expressed if there is a dominant gene for that allele present. This means that if a female (XX) is expressing an x-linked recessive trait, she must have two recessive genes for that trait; therefore she inherited the trait from both parents.
Is color blindness a dominant or a recessive trait?

Sex-linked and Recessive
How does a person inherit hemophilia and is it dominant or recessive?
It is a sex-linked recessive trait inherited from the mother.
Are sex linked traits dominant or recessive?
They can be either or depending on the trait.
Why are x linked alleles expressed in males even if they are recessive?
X-linked are not recessive nor dominant. X-linked just do not show. On the sex-linked chromosomes the Y chromosome of the X-Y pair dominates the trait whether its recessive or dominant!Actually, all x-linked alleles are expressed because males only have one x-chromosome, so whatever is there, dominant or recessive, is expressed.
Why are heterozygus individuals called carriers for non-sex-linked and X-linked recessive patterns of inheritance?
Aa. This is the heterozygous condition. Two alleles, one of which is dominant and masks the expression ( to varying degrees ) of the other allele. 'A' dominant and 'a' recessive. So, if the trait in question is the recessive allele the dominant allele masks its expression and the organism is a ' carrier ' of the trait and can pass it on to progeny.
Are sex linked traits dominent?
Some are dominant ... some of the most noteworthy negative ones: color blindness, hemophilia are recessive.
What sex link is a recessive disorder?
Muscular dystrophy is a sex-linked recessive disorder.

Who always wins a dominant gene or a recessive gene?
The dominant gene always win because it is represented by upper case letters. And the recessive genes loses all the time because it is represented by a lower case letter.A dominant gene in most cases. If it an autosomal trait (on body cells) in all cases the dominant gene will win. In the case with x, sex linked recessive traits the recessive trait will appear in males if only one gene is presentA dominant gene in most cases. If it an autosomal trait (on body cells) in all cases the dominant gene will win. In the case with x, sex linked recessive traits the recessive trait will appear in males if only one gene is present
