Which sex is most likely to be affected by a negative Y linked recessive trait?

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."

Is Autism X linked?
Autism is not traditionally x-linked. If it were x-linked dominant, all females of an affected father would have it (since they always get one x from their fathers). If it were x linked recessive, then it would skip a generation and NO male sons of an affected father would have Autism. There is evidence that there is a relation to sex, given the increased ratio of affected boys to girls, but it's a complicated mix of genetic and nongenetic causes (i.e. imprinting of genes, comorbid diagnoses).
What gender is affected by sex linked traits?
Males are more likely to receive a sex-linked genetic trait because they have only one X chromosome. A certain trait on a woman's X may be covered up by another trait on her other X, men only have one X so they are stuck with whatever trait appears on it.
What is a sex-linked linked genetic disorder?
color blindness is one
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.
How do you recognize a pedigree for an x-linked recessive allele in human beings?
For a recessive sex-linked trait to manifest in women it would have to be in double dose (XaXa) while for men in single dose (XaY). Women carriers would have one of each but would not be affected (XAXa). Knowing this it's quite easy to spot pedigrees where this kind of inheritance occures.Heterozygote mothers (gene carrier) can have sons that are affected (50% chance);Affected mothers have only affected sons (100%);No first generation daughter of an heterozygote mother will be affected but there is a 50% chance that she is a carrier;Affected fathers with normal mothers will have zero sons that are affected but all their daughters will be carriers;
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.
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 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
Is muscluar dystrophy sex-linked?
Yes, it is X linked recessive.
Since red - green color weakness is recessive and sex linked the incidence of this color weakness is likely to be greatest among what?
Males
What is the most likely mode of transmission for a trait that is not expressed in parents but is expressed by one half of the sons?
