Medical Definition of X linked disease
1.
A genetic or inherited disease whose controlling gene or at least part of the relevant genome is carried on an X chromosome, for example haemophilia. most known conditions are recessive and thus since males have only one X chromosome they will express any such recessive character. Few dominants are known and the homozygous states are very rare so that female expression of such diseases is uncommon.
