Mitochondria also has it's own separate DNA

It's believed that mitochondria were once individual prokaryotic organisms, but were phagocytized and adapted for energy-generating purposes by early eukaryotic organisms. Also, mitochondrial DNA is the only genetic material that comes entirely from one parent. Our mitochondrial DNA is the exact same as our mother's, since sperm cells do not contain mitochondria.

Sperm cells contain many many many mitochondria, it's how they get the energy to keep swimming without dying for like 3 days. But you're right in that we inherit mtDNA from our mothers.

"While female eggs contain lots of mitochondria, male sperm contains only a few, which are lost after fertilization."

I was wrong, they do have some mitochondria, but not many. They all are just degraded when fertilization occurs, and the genetic information in the sperm is the only thing that is transferred and used.

Every goddamn cell has genetic material

Oh honey, you must be confused. Mitochondria are organelles inside a cell, not individual cells themselves. Please try to pay a little more attention in your next science course.

well... but he isn't wrong... just out of context
