https://en.wikipedia.org/wiki/Human_mitochondrial_genetics#Replication,_repair,_transcription,_and_translation https://en.wikipedia.org/wiki/Human_mitochondrial_genetics#R... : Mitochondrial replication is controlled by nuclear genes and is specifically suited to make as many mitochondria as that particular cell needs at the time. : Each human cell contains approximately 100 mitochondria : The amount of mitochondria per cell also varies by cell type : Egg cell: Mature metaphase II egg cells can contain 100,000 mitochondria (so when it comes to passing down mitochondria to descendants, eukaryotes don't fool around)
