how is the expression of sex linked genes both similar to and different from the expression of autosomal genes?

first of all you are already known about the genes found in male and female Autosomal genes are not expressed by the X or Y chromosome. Sex linked genes are expressed by the X or Y chromosome. Expression of autosomal and sex-linked genes are the same in that both require undergo meiosis and crossing-over may occur and transcription and translation of genes are required.

Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female and one X plus a Y result in a male.

In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
These traits will be inherited according to the sex chromosomes they receive from their parents. Women recieve one X from the mother and the other from the father while men recievethe X from the mother and the Y from the father).

This will cause a difference in the expression of genes because women can become carriers of a certain disease while men either manifest it or don't (there are no carriers since the X chromossome is different than the Y)

In autosomal genes, the expression doesn't depend on the gender since the autosomal chromosomes contain genes that code for the same trait, and so the expression on autosomal genes in men and women are similar.
