So, I'm not really any kind of trained botanist. But I do have two things: some dandelion seeds from France, and, collecting dust in my garage along with related accessories, this thing.
Normally, the dandelions growing in an American yard are apomictic triploids, but in Europe there's both triploids and sexual diploids, the latter getting even more common the further south. I'm assuming that, because these French seeds are a specific common cultivar (Vert de Montmagny), that regular sexual selection was used in breeding it, making it a diploid. But I don't know who to ask to confirm this so I may as well do some testing. If it's a diploid, maybe I can do some breeding of my own?
But I don't even know the first step. Are there some parts of a plant that I'll have an easier time finding chromosomes in? What do I put them in to express their DNA and what do they best stain in? Would I even be able to discern the different chromosome shapes without training? I've heard the standard science project way to extract DNA (dish soap, salt, alcohol) damages the chromosomes so that you wouldn't really find them in a microscope; if true I hope there's another way.
