Why are genetic diseases carried by genes on the X chromosome more common in male offspring than female offspring?

Because in males they have only 1 X chromosome. The other one is Y.
But in females they have 2 XX chromosomes so the chance that X chromosome will carry disease to cause illness is lower.
Example: lets say xx (recesssive) phenotype makes illness, whereas XX (dominant) is healthy.
A woman can have XX, Xx, xx right? Since Xx is a carrier and XX is healthy you wont see the illness. only xx can make illness. 1/3 chances she is sick.
However in males they have XY. so he can only have either XY or xY. No carrier form is present. The chances he will be sick is %50.
got it?
Im a genetic engineer and molecular biolog so count on me :)

Genetic information is carried from the chromosome to the ribosome by the?
Messenger RNA.
What is a function of chromosomes?
A chromosome is transferred from parent to offspring and its purpose is to transport genetic material to the cell of the offspring
What kind of conditions is carried on a chromosome other than the sex chromosome?
This would be just a genetic or inherited condition.
Are there characteristic attached to the sex chromosomes other than gender?
Genetic diseases are often carried on the X chromosome. For example, hemophilia or colorblindness. Also, there are genes needed for the development of a fetus on the X chromosome. Scientists don't know their location, but they do know that a baby cannot be born without an X chromosome.
How come there are no carriers in genetic diseases caused by dominant alleles?
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.
If a genetic disorder is carried on a recessive gene which if any will have the disorder?
If a genetic disorder is carried on a recessive gene, offspring will only have the disorder if both parents have the recessive gene.
How does something pass its characteristics to its offspring?
By the combination or recombination of genetic traits carried on its DNA
What kind of conditions is carried on a chromosome other than sex chromosomes?
This would be just a genetic or inherited condition.
What kind of conditions is carried on a chromosomes other than the sex chromosomes?
Sickle cell anemia and cystic fibrosis are carried on autosomes (chromosomes other than the sex chromosomes). Probably too many to list . . Right now, off the top of my head, I can think of Down's Syndrome (21st chromosome) and the "cri du chat" (5th chromosome) . . .
What is the defintion of chromosome?
A chromosome is a threadlike structure of nucleic acids and protein found in the nucleus of most living cells. Genetic information in the form of genes are carried by chromosomes.
Is it true carriers of genetic diseases who do not have the disease themselves have recessive genes for the disorder?
Yes. They can pass it on to their offspring.
The genetic information that is passed from a parent to its offspring is found in?
Most of the genetic information that is passed form a parent to its offspring is found in DNA molecules.
