Not a very good question on my part in the first place.
Veda- ta, `tis good to know.
Cerebro- so as I understand it some cannabis cells (the gametes- pollen and ovules) are haploid which means they have just one set of 10 chromosomes. Whereas the other diploid (unless they are polyploids

) ones have pairs, adding up to 20 chromosomes.
I think I was assuming that diploidy meant the chromosome pairings were identical (homozygous).
