Genetic Inheritance Mechanics
The "2+2" Passive Skill Rule
In Palworld, breeding with parents that have exactly 2 target passives each (and zero junk traits) gives the highest statistical chance (~10.2%) of hatching a perfect 4-passive god-roll Pal.
Parent 1: 2 Target Traits
e.g. Legend + Musclehead
Parent 2: 2 Target Traits
e.g. Ferocious + Burly Body
Child: 4/4 Perfect Roll
