I am Doing an experiment on extracting DNA from onions. Why/ How are onions different? and what does that have to do with starch?

Well its an environemt thing, and a DNA thing. Onions from a grocery shop are unlikely to have come from the same seed onion, whereas 2 onions pulled from next to each other could be related.
Environmentally, if one was growing in a more nutrient rich area, or more optimally watered then it will grow bigger (as with if its less shaded).

I know, its a dubious reply at best, but come on, its a fricking onion - I cant even remember how they grow (despite the fact we have them growing in the fields around my house)
Is it one onion per tall leafyness, or several...
