The lymphatic system can be defined as a system of network of tissues and organs that helps the body to clean toxins and other materials of the body that is not required.
The main function of the lymph is to transport lymph, which is a fluid that helps in fighting with infection.
The pathway that is followed by the lymphatic system inside the body is lymph nodes→ lymph vessels→lymph capillaries→ subclavein veins.
Those mutated genes are most commonly recessive. Females have two X chromosomes so they can have a chromosome with the mutated gene and one with the healthy gene. The healthy gene is dominant so the disease won't manifest, and the woman is only a carrier. Males have only one X chromosome and an Y chromosome. If they have the mutated gene on the X chromosome they won't have another X chromosome with the healthy gene.
To summarize, men can't be carriers and they only need one copy of the mutated X-linked gene while women need two copies of the mutated gene.
