I decided to "show ignored content" of this thread, and quickly remembered why I ignored it to begin with. That said, the arrogance in this thread is astounding!
It's not bro science, and frankly it has to do more with genetic mutations than anything. It's proven science that identical human twins aren't really identical because of the many mutations which occur after the fertilized egg divides. Old science believed that the difference in twins had more to do with environmental impacts, and although it is true that environment does play a role, newer science has discovered that it is more attributed to the aforementioned mutations. It's really not much different in Cannabis clones vs humans, in that dna mutations do happen all the time. I personally have experienced it myself with a specific cut in the past.
Here are two scientific articles to support my assertion (not Leafly, derp):
A new study of plants that are reproduced by 'cloning' has shown why cloned plants are not identical. Scientists have known for some time that 'clonal' (regenerant) organisms are not always identical. Now researchers believe they have found out why this is the case in plants: the genomes of...

Cannabis is typically propagated using stem cuttings taken from mother plants to produce genetically uniform propagules. However, producers anecdotally report that clonal lines deteriorate over time and eventually produce clones with less vigour and lower cannabinoid levels than the original...
