Mitochondria are central to eukaryotic life. Mitochondria retain their own genome (mtDNA) and this molecule has important roles in energy production and a growing list of other processes. Mitochondrial DNA is almost universally inherited solely through the female lineage, which provides opportunity for selection to operate asymmetrically between males and females. A growing body of work suggests strongly that mtDNA mutations may have stronger effects on phenotype in males than females – an idea I termed 'Mother's Curse'. In this theory talk I will review the development of the Mother's Curse hypothesis and the still accumulating evidence that supports it. I will also explore some areas in evolution and ecology where this theory might have impact or application, including a new form of biocontrol.
