Mitochondrial DNA in most multicellular organisms is inherited from the mother during fertilization.
Is it true that mitochondrial DNA in most multicellular organisms is inherited from the mother during fertilization?
Yes. The vast majority of scientific literature affirms that mitochondrial DNA in most multicellular organisms is predominantly inherited maternally, though rare instances of paternal leakage can occur under specific conditions such as distant hybridization.
Verdict: SUPPORTED · 5 sources for, 1 against · Last checked
The retrieved papers overwhelmingly support the standard biological consensus that mitochondrial DNA is maternally inherited across most multicellular taxa, driven by active evolutionary and cellular mechanisms designed to eliminate paternal mitochondria. While a few exceptional cases like hybridization-induced paternal leakage are documented, the primary weight of evidence remains overwhelmingly in favor of maternal inheritance.
