It was my understanding that in animals, plastid (mitochondrial) DNA is
not contributed from the sperm at all to the new zygote. The mitochondria are
all clustered back in the tail, and only the head fuses and ejects its
nuclear material into the egg. Thus (at least in humans, hence the dating
of "Eve" that caused a fuss a couple of years ago) all mitochondria are
transmitted through the female by simple mitotic divisions.
