it's either by guessing, contacting the original grower/seller, or genetic testing...so in guessing it is more about what you believe it is unless you are going to go for one of the other two. not exactly a positive ID just a likely one
I would take it even if it is a noid. What a nice list. I wish I knew how big some of them are. The yellow with the red strips about half way down looks just like the mini one I gave my mom and my sister.
The one that mine is a peloric, the one in my avatar. The bloom is identical.
Definitely not a positive ID. The only way to obtain such is to contact the vendor who hopefully knows or the breeder. (Don't see anyone caring enough to the expense of genetic testing. )
