Every waifu carries a real 41-locus genome. Hair color, race features (cat ears, horns, wings, tails), build, personality quirks, even her preferences — all resolved from her actual genetic data. Her portrait is AI-generated from that genome, not bolted on top. Two waifus never share the same genetic fingerprint.

Five tiers, from common to apex:

Basic — fast hatch, mostly human traits
Variant
Adapted
Evolved
Apex — the wait gets longer, the genome gets weirder
A 5-minute egg can crack open an apex. A 4-hour wait can hand you a basic. The timer tells you nothing useful. I run this lab long enough to know that waiting makes the opening better.
