Could Dad’s Mitochondrial DNA Benefit Hybrids?
Alejandra Manjarrez, PhD | Jan 20, 2022 | 7 min read
Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.

Cataloging Life Can a single barcode of DNA record biodiversity and keep us safe from poisons? By Bob Grant Related Articles 1 for soil nematodes, barcoding's genesis lies in a 2003 paper in Proceedings of the Royal Society of London2 by Paul Hebert, a Canadian researcher who some call "the father DNA barcoding," and colleagues. In that paper, Hebert's team proposed a universal animal barcode: a segment of roughly 650 base pairs of the mitochondria
