What kind of boa is this ? (need help)

[Tingya]

Hello,

I have had a ball python for 2 and a half years now. I just got a new 6 months old boa as a present yesterday. I was wondering what kind of boa that is because I read that there are different types, BCCs BCIs etc...

Could someone help me identify this one ?

Also I heard popping was really a bad method to identify the gender of a boa, is that true ? I did that myself for my ball python 2 months after I got it since there are no vets specialized in reptiles where I live in Taiwan, and if I tried to bring my boa to a vet, they'd probably try to kill it or eat it hehe

Thank you !!
