Step 1
In humans, mtDNA is inherited solely from the mother. This is because the egg cell contributes the majority of the initial cell's cytoplasm, which contains the mitochondria, while the sperm contributes very little cytoplasm. Show more…

why it is that we inherit mitochondrial DNA ONLY from our mothers?
Madhur L.
Explain the significance of mitochondrial DNA (mtDNA) and Y chromosome DNA in lineage tracing.
Mitochondrial DNA can be taken from bone, hair, or teeth and used in DNA typing. What are the benefits of using mitochondrial DNA over nuclear DNA? mtDNA requires a much smaller sample than nuclear DNA. mtDNA is useful if the nuclear DNA is degraded. mtDNA is inherited from the mother and father's egg cells, unlike nuclear DNA. mtDNA is present in all maternal relatives of the person being investigated.
