Hey guys,
I started watching the deep dive on Di-mon. Super stoked y`all are tackling these more complex and fascinating topics and simplifying it just enough so more of us who haven't gone into the more advanced aspects can also get stoked about it.

I heard something in the beginning that I wasn't sure was correct, so I wanted to check, cause maybe my own understanding is off. 

Towards the beginning, Gregory said something along the lines of "If they like each other, they will become dikaryotic There will be plasmogamy, but won't be fusion of cytoplasm, just sharing of nucleus." Did he mean there won't be fusion of nucleus, just sharing of cytoplasm? My understanding was that with plasmogamy there is sharing of protoplast (cytoplasm and organelles) but not yet the fusion of nuclei, which happens during karyogamy. 

Does anyone have experience sending strains abroad (not through a company)? I feel like they are gonna get very suspicious at customs, since it is biological material, and they won't let it through. 
I want to send cultures to Portugal. My plan is to try both by mail and, if that fails, in my suitcase. The method I'm gonna try is 5 ml cryovials with agar plugs in distilled water, but if there is a better method to fly under the radar, I would like to know.
Anyone have specific tips or experience with this?
I appreciate it as always.
