big mystery to me is when the y chromosome actually came into play. all dioceious plants start as mono and mono cannabis are all xx. theres a progression from mono to dio during which self fertile populations size has to shrink to force plant into diversifying into 2 sexs.
xx mono self fertile
xx loses fertility thru a transitionary period a numbers game wherein portions of population are self fertile but others are not a grey period of high diversity before the sex chromosomes are s
xy
genome sizes- this study also found triploid males in uttakarhand a 4 way intersection of drug cannabis china/nepal/india/mynamar/bhutan
once the split is complete at some point the y chromosome has seperated itself with non recombining
the closer a population is phylogenically and enviormentally to the middle transition half/half period the more monoceious genes/phenotypes will remain. thailand fits this description. not to mention se asian genome content has been found to be much larger then domesticated types some amount of unsettled genetic processes are present. even more interesting recently a cbga synthase gene was found on the x chromosome!
