We used both broken and intact mitochondria preparations, and I'm wondering what the significance in this is.
Thanks!

I just read about Komodo dragons and how there have been reported parthenogenesis. They even tested the eggs some how and determined that there was no signs of outside fertilization. So is it not entirely impossible to have a "virgin mary" ? How do they test if there's no outside influence and is it really the difference between "ZW" chromosome and the "XY" chromosome... what's the difference? could "mary" be a freak and have a "ZW" instead of "XY"
