Ideas of questionable quality

[Danger Noodle]

New Chromosome idea
Inverter, makes it so the mutation does the inverse of what it would normally do.
IE, Regen becomes passive hurting instead of healing.
Nectar Perspiration makes it so you don't have small bees attack you, but normal bees hate you.
fire breath becomes cold breath and cryokinetics becomes pyrokenetics.

Honestly would love to see something like this but the only problem I could see with it is that you can't combine other chromosomes with it, it could be changed into an upgrade you research but maybe it's best to leave it uncombinable with other chromosomes as some of them could be really debilitating.
