Men have 1 X chromosomes and Women have 2. This means, that men are more affected by the x linked recessive disorder as they only have one chance to get a non mutant allele. See the wikipedia extert below for more info.
"In humans, generally "men are affected and women are carriers" for two reasons. The first is the simple statistical fact that if the X-chromosomes is a population that carry a particular X-linked mutation at a frequency of 'f' (for example, 1%) then that will be the frequency that men are likely to express the mutation (since they have only one X), while women will express it at a frequency of f2 (for example 1% * 1% = 0.01%) since they have two X's and hence two chances to get the normal allele. Thus, X-linked mutations tend to be rare in women."

What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
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.
Is an x linked dominant trait the same as an x linked recessive gene?
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.
Are sex linked traits more or less likely to show up in males?
Sex-linked traits are more likely to show up in males because they are located on the X chromosome. Males only have one X chromosome, so a recessive allele on the X chromosome will be expressed, whereas females have two X chromosomes and would need to inherit two recessive alleles to express the trait.
Why were heterozygous individuals called carriers for non-sex-linked and x-linked recessive patterns of inheritance?
I don't know and don't care
In X-linked recessive inheritance what sex is the affected?
There are 2 X-linked recessive inheritance where Only Male or Men are the only people who inherits these kind of trait.
How do you know if a trait is sex linked dominant or sex linked recessive?
A trait is sex-linked dominant if it appears in every generation and affects both males and females. It is sex-linked recessive if it skips generations, more common in males, and passed from carrier females to affected males. Mendelian inheritance patterns can help determine if a trait is sex-linked dominant or sex-linked recessive.
What is the pattern of inheritance for a sex-linked recessive trait in a pedigree?
In a pedigree, a sex-linked recessive trait is passed down from carrier mothers to affected sons. Daughters of carrier mothers have a 50 chance of being carriers themselves. Sons of affected fathers do not inherit the trait.
Why are sex linked recessive conditions more likely in males then females?
Sex-linked recessive conditions are more likely to occur in males because they only need to inherit one copy of the affected gene in order to exhibit the condition (as they have one X chromosome). Females, on the other hand, have two X chromosomes, so they need to inherit two copies of the affected gene to exhibit the condition.
Is color blind dominant or recessive?
recessive
Are sex linked traits dominent?
Some are dominant ... some of the most noteworthy negative ones: color blindness, hemophilia are recessive.
Why are males more likely to get recessive sex linked disorder?
Males are more likely to get recessive sex-linked disorders because they have only one X chromosome, meaning they will display the disorder if that X chromosome carries the recessive gene. Females, on the other hand, have two X chromosomes which can often mask the presence of the disorder if one X chromosome carries a normal allele.
Why are males more likely than females to have a sex linked traits that are recessive?
Because they olny have one X chromosome.
Why are males more likely than female to have a sex linked trait that is recessive?
Because they olny have one X chromosome.
What are the four complex patterns of inheritance?
Autosomal dominant, Autosomal recessive, X-linked recessive and X-linked dominant
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.
Is muscluar dystrophy sex-linked?
Yes, it is X linked recessive.
