Where do autosomal traits and sex-linked traits exist?

Question

Isabella Anderson · Accepted Answer

Autosomal traits exist in all the chromosome pairs (1-22) except X and Y; sexlinked traits only exist on X and Y and expression depends on the sexx of the offspring.

Autosomal dominant traits: An offspring will display a trait if they inherit the recessive form on one chromosome and the autosomal dominant trait on the other (dominant on 10 and recessive on the other 10). Autosomal recessive traits: To display the recessive trait, an offspring needs to inherit two recessive forms of the gene on each of the chromosomes in a pair—one recessive on chromosome 10 and another on chromosome 10. A female would have to inherit two X chromosomes with the recessive gene in order to exhibit that trait; consequently, her father would also show the same trait but her mother might not. Men have only X and Y, where women have to X's. All traits on Y chromosomes will be expressed by all men in that family; there is no dominance/recessiveness. Sexlinked traits depend on the sexx of the offspring.

undefined Sex-linked traits are found on sex chromosomes, specifically the X and Y chromosomes, while autosomal traits are found on autosomes, which are non-sex chromosomes.
