However, a father cannot pass X linked inheritance to a son since the son receives only Y chromosome from his father. Moreover, males show severe symptoms of the X linked dominant disorder than females. Some X linked dominant disorders are lethal in males. Only one copy of the mutant gene is sufficient for the disease to occur in both males and females. X linked dominant is a disorder caused by a mutation in genes on the X chromosome. Side by Side Comparison – X Linked Dominant vs X Linked Recessive in Tabular Form Similarities Between X Linked Dominant and X Linked Recessiveĥ. Females that carry one recessive mutant gene in one X chromosome are carriers. But in females, one copy of the mutant gene is enough to cause the X linked dominant disorder while two copies of mutant genes are needed to cause the X linked recessive disorder. In males, one copy of the mutant gene is enough to cause X linked dominant or X linked recessive disorders. Females have two X chromosomes, while males have only one X chromosome. The genetic disorders occur due to the mutant genes located in X chromosomes. The inheritance is due to the genes located on X chromosomes. X linked dominant and X linked recessive are two types of X linked genetic inheritance. The key difference between X linked dominant and X linked recessive is that X linked dominant is a genetic disorder caused due to a dominant mutant gene located on the X chromosome while X linked recessive is a genetic disorder caused due to one or two recessive mutant genes located on the X chromosomes.
