Answer:
The inheritance of mitochondrial DNA (mtDNA) is matrilineal, it means that an organism inherits the mtDNA from its mother
Explanation:
The phenomenon of matrilineal inheritance has deep genetic implications since it enables the study of phylogenetic lineages of the species (or among populations within the same species) by analyzing mitochondrial inheritance.
It should be noted that mitochondrial genes aren't typically heterozygous because the DNA are inherited exclusively from the mothers.
Mitochondrial genes typically contain genome and they instruct cells to produce subunits of the enzyme.
Individuals are not typically heterozygous with respect to mitochondrial genes. Mutation can only lead to a state of heteroplasmy.
