Odds favor X-linked diseases because everyone has a least one X chromosome as opposed to a Y which only 50% (males) have. Since women have two Xs, they are less affected by X-linked diseases too, because they have likely inherited one perfect X from one parent and one damaged X from the other, where a man only has one X from his mom so if it's damaged he's going to have the disease expressed when his sister might not or have a milder version of the same disorder.

Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.
If a characteristic is sex-linked then where is the gene for it found?
Genes for sex-linked traits can be found on the sex chromosomes - X and Y. Almost all sex-linked traits are determined by the X chromosome, because it is much larger than the Y chromosome and can thus carry more genes. A few sex-linked traits are known on the Y chromosome, including - believe it or not - hairy ears.
Why males are affected more then females by sex linked disorders?
In humans males sex is determined by the presence of the Y chromosome. This is a very short compared to the X chromosome with which it is pair. Therefore if there is a genetic defect on the X chromosome then it cannot be masked by a beneficial one on the Y as it is simply not there.
Is Klinefelter Syndrome sex-linked or autosomal?
Klinefelter Syndrome is sex-linked, because it is a genetic defect that results in a male having an extra X chromosome.
Why can females but not males be carriers of sexlinked genetic disorders?
Several genetic disorders are caused by genes on the X chromosomes.
Why do more males end up with sex-linked disorders?
More males than females end up with sex-linked disorders because of the y chromosome. It is shorter than the x-chromosome, and increases susceptibility to these problems.
Why are males often affected more than females by sex-linked genetic disorders?
males have only one X chromosomes
What sex is more likely to get a sex-linked disorder?
Many sex-linked disorders come from the X chromosome. (Either gender can obtain the disorder, however, it is harder for a female to get it than a male). Very few sex-linked disorders occur on the Y chromosome. (Only males can obtain these disorders).
Which chromosomes are more sex-linked disorders found on?
In humans it would be the X chromosome.
What are sex-linked disorders?
Disabilities or disorders that are linked to reproduction or sex For more info GOOGLE IT!

Why do X linked genes have a different inheritance pattern than autosomal disorders?
Because ur stupid
Why are boys mostly miscarriages at birth than girls?
Likely due to the large number of x-linked genetic disorders.
What is a sex-linked disorder and give one example?
Genetic disorders that are linked to either the X or the Y chromosomes. Red-green colorblindness and hemophilia are both sex-linked disorders.
Why is it that males show sex-linked disorders easier than females?
Because most of the sex linked inheritance is in X linked rececieve gene. When that rececieve gene is carried to produce boy baby, the traits which are present in X rececieve will be co- dominant to Y.
What is more likely to happen to males because they have only one X chromosome?
sex-linked disorders
What are x linked traits?
i think it is not not because its not a not of decision not because it is cells and disorders.
