Polyploidy isn’t the same. If a plant were any number, say diploid, wouldn’t look different structurally. Instead it would contain two completely divergent genetic expressions. Often mistaken from pictures that were labeled as diploid or triploid because of the number of bracts in the mutation, but they were mischaracterized whorled phyllotaxy irrespective of the number of bracts involved in the mutation. Like you said before they tend to work themselves out but could bud in a mutated way also. A diploid could have branches of different expression alternating. Could be genetically verified, a normal cannabis plant contains its full genetic code in the apical meristem, polyploidy will have full non-matching genetic code off meristem.
