Final answer:
Mitochondrial inheritance involves maternal inheritance, heteroplasmy, and random segregation during cell division.
Step-by-step explanation:
It is true that mitochondria are maternally inherited, which means that mitochondrial traits are encoded by mitochondrial DNA (mtDNA).
In addition, heteroplasmy is also a characteristic of mitochondrial inheritance. Heteroplasmy refers to the presence of more than one type of mtDNA within an individual, which can result in variations in mitochondrial traits among cells.
Lastly, the mitochondria segregate randomly as cells divide, leading to differences in the distribution of mtDNA among daughter cells.
