binnie-mods-1.12.2-2.5.0
forestry_1.12.2-5.7.0.219

To reproduce:

• disable a module that registers with Binnie's genetics in the config (so far tested with lepidopterology and aboriculture) in forestry config
• launch minecraft

crash report: crash
I fixed the top line of this (I think) by changing loadalleles to only search active breeding systems.
I then got this crash-2017-12-30_00.47.13-client.txt so I'm guessing this runs pretty deep. I don't know if this is an issue for Binnie's or forestry (ForestryMC/ForestryMC#1927) but it seems pretty problematic. Then again, disabling modules causes a lot of problems so maybe Binnie's should just require all forestry mods be enabled.

Hope this helps.

EDIT: Disabling aboriculture gives the same crash crash-2017-12-30_16.48.04-client.txt

EDIT2: #352 has similar error

This is the same as #331 which has been fixed.
