ABSTRACT
In contrast with nuclear genes that are passed on through both parents, mitochondrial genes are maternally inherited in most species, most of the time. The genetic conflict stemming from this transmission asymmetry is well-documented, and there is an abundance of population-genetic theory associated with it. While occasional or aberrant paternal inheritance occurs, there are only a few cases where exclusive paternal inheritance of mitochondrial genomes is the evolved state. Why this is remains poorly understood. By examining commonalities between species with exclusive paternal inheritance, we discuss what they may tell us about the evolutionary forces influencing mitochondrial inheritance patterns. We end by discussing recent technological advances that make exploring the causes and consequences of paternal inheritance feasible.
