title: Eliminating mitochondrial DNA from sperm.
abstract: Most eukaryotes show uniparental inheritance of mitochondrial DNA (mtDNA). In this issue of Developmental Cell, DeLuca and O'Farrell (2012) show that active elimination of mtDNA during sperm development in Drosophila ensures that mature spermatozoa are devoid of DNA.
