science rox Posted April 29, 2006 Share Posted April 29, 2006 can't figure this out; what is the difference between genetic and sex linked diseases Link to comment Share on other sites More sharing options...
alt_f13 Posted April 30, 2006 Share Posted April 30, 2006 Do you mean sexually transmitted diseases, or diseases that might have more of an impact on one sex than the other? Genetic diseases may be passed down through the family line; diseases, which, due to certain genes passed on from parent to child, are more likely to be contracted by someone with those genes, or are themselves abnormalities that may be passed on from parent to child. An example of a sex-related disease would be breast cancer, which is much more likely to pop up in a woman. A sex-specific disease would be something like cervical cancer, which a man can't get at all. You can look them all up on wikipedia.org. Link to comment Share on other sites More sharing options...
zyncod Posted April 30, 2006 Share Posted April 30, 2006 I think you mean Mendelian vs. sex linked diseases. And it all has to do with the X chromosome. Link to comment Share on other sites More sharing options...
Yggdrasil Posted April 30, 2006 Share Posted April 30, 2006 A sex-linked disesase is a specific class of genetic diseases. The alleles for sex-linked diseases are located on the X-chromosome so recessive sex-linked diseases (such as hemophilia or color-blindness) occur more commonly in males (who must possess only one copy of the disease allele) than in females (who must possess two copies of the disease allele).

chuinhen Posted April 30, 2006 Share Posted April 30, 2006 and is it mean that is always the X chromosome that carriers the reccesive gene that responsible for the sex-linked disease ?? Link to comment Share on other sites More sharing options...

Well, it's the price you pay for being male. Feminism to the contrary - and I am all for it - men live hard and die young. The fact that you don't have two Xs just adds to that.

zyncod Posted May 3, 2006 Share Posted May 3, 2006 That's generalizing a bit, don't you think? Um, yes. The life expectancy for males is seven years younger than women in the US. But that's what statistics are for: generalization. Link to comment Share on other sites More sharing options...
