Passives can pass from a parent to its offspring during breeding, and which ones make it through is partly random. The odds are well understood from community reverse engineering of Palworld 1.0: a child directly inherits 1 to 4 passives from the parents pool (40/30/20/10 percent for exactly 1/2/3/4), then 0 to 3 random passives can be added on top (40/30/20/10 percent for 0/1/2/3). The Breeding Calculator now turns those constants into per-egg odds and an expected egg count for the exact passives you are hunting.
