Unlinked

Genotype

The genetic makeup of an organism, consisting of all the DNA and genes present within its genome.

Dosage Compensation

Genetic mechanism by which the expression of X-linked genes is made equivalent in XX females and XY males; in mammals this is accomplished by rendering all but one X chromosome inactive.
