The matrilineal most recent common ancestor of all living people is believed to have lived about 140,000 years ago based on the molecular clock technique of correlating elapsed time with observed genetic drift.
Mitochondrial DNA comes from the mother, so the mother's maternal line and all her children share the same mitochondrial DNA.
In most organisms, including humans, the mitochondrial DNA is inherited from the mother.
Some associated genes of human mitochondrial genome are the Eukaryotic cells and the cell nucleus. Mitochondrial DNA is inherited only from the mother's ovum.

Mitochondrial DNA (mtDNA) is inherited exclusively from the mother because the mitochondria in the sperm are typically destroyed during fertilization. This means that all the mitochondria in the developing embryo come from the egg cell. As a result, the offspring's mtDNA is a direct maternal lineage, reflecting the genetic material passed down from the mother.
Mitochondrial DNA is almost universally inherited from one's mother. I heard of a case of a man in Italy inheriting his mitochondrial DNA from his father, but I consider it likely he was also sterile--if indeed that did occur.
Mitochondrial diseases are exclusively inherited from the mother because mitochondria, the energy-producing structures in cells, are passed down from the mother's egg cell to the offspring. Sperm cells do not contribute mitochondria to the embryo, so any genetic mutations in the mitochondria will only be inherited from the mother.
Because all our mitochondria are descended from those in our mother's egg cells.
Mitochondrial DNA is only inherited from the mother, while nuclear DNA is inherited from both parents. Mitochondrial DNA is circular and does not undergo recombination, whereas nuclear DNA is linear and can recombine during meiosis. Mitochondrial DNA codes for a small number of genes related to energy production, while nuclear DNA contains genes that determine various traits and characteristics.
Mitochondrial DNA is passed down from the mother to her offspring. This type of DNA is found in the mitochondria, which are structures found outside of the cell nucleus. Mitochondrial DNA is inherited exclusively from the mother because only the egg cell contributes mitochondria to the developing embryo.
Mitochondrial DNA is passed from mother to daughter because during fertilization, the sperm typically donates very little, if any, mitochondria to the zygote. This results in the mitochondrial DNA being inherited solely from the mother. It is the egg that contributes the majority of the mitochondria to the embryo.
Mitochondria have mitochondrial DNA inherited through the cytoplasm of the mother.
