Paternal mitochondria and membraneous organelles can be visualized after fertilization. Mitotracker labelled males were mated to hermaphrodites expressing GFP::Ub. Embryos were imaged via confocal microscopy after fertilization and Z stacks were collected. Maximum projection images are shown. The ubiquitinated MOs (green) are closely associated with the sperm mitochondria (red) until the completion of maternal meiosis. As the embryo enters mitosis, the MOs and mitochondria become dispersed.
