State
Mitochondrial genomics studies mitochondrial DNA, which mutates rapidly and passes from mother to offspring, making it useful for tracing genealogy and evolution.
Show
A child inherits mitochondrial DNA only from the mother, so tracing that sequence across generations reconstructs a maternal-line genealogy.
Watch for
Mitochondrial DNA's maternal inheritance makes it useful for tracing lineage — it does not track paternal-line ancestry as nuclear markers can.
