The genotype of sterile male tortoiseshell cats. Concept introduction: All humans and other mammals contain sex chromosomes such as XY in males and XX in females. The genes present on the X-chromosome are X-linked genes. The activity of a single X chromosome is normal. The males have this normal dosage, as they have one X chromosome. In females, one X chromosome is inactivated for normal dosage. This is known as X-inactivation.
