what is the pattern of inheritance of mitochondrial dna?
Examples: colour blindness, ocular albinism, choroideremia. A fourth type of inheritance considered in ophthalmic practice is mitochondrial (maternal) inheritance in which the inheritance of a trait encoded in the mitochondrial DNA is transmitted through the female line (mother to son or mother to daughter). Examples: Leber's hereditary optic atrophy; Kearns-Sayre syndrome.
