Detailed explanation-1: -Sex-linked genes are that are present on the sex chromosomes and that determine the sex-linked traits and are transmitted from parent to progeny through sex chromosomes only. Chromosome other than sex chromosome is referred to as autosome which controls normal traits of an organism, not the sex-specific traits.
Detailed explanation-2: -These are sex chromosomes because they differ between the sexes. In humans, males have one of each while females have two X chromosomes. Autosomes are those chromosomes present in the same number in males and females, while sex chromosomes are those that are not.
Detailed explanation-3: -Having to do with any of the 22 numbered pairs of chromosomes found in most human cells. Autosomal chromosomes are numbered 1-22. The sex chromosomes (X and Y chromosomes) determine whether an individual is male or female and are not considered autosomal chromosomes.
Detailed explanation-4: -The numbered chromosomes are the only chromosomes that use autosomal inheritance patterns.
Detailed explanation-5: -And in humans this is the X or the Y chromosomes. And so some of the more familiar sex-linked traits are hemophilia, red-green color blindness, congenital night blindness, some high blood pressure genes, Duchenne muscular dystrophy, and also Fragile X syndrome.
