An inbred young has every gene weaker (gene position × 0,5) — even a Good one works like Ok.

How it works

  • Each of the five genes has two copies: Good, Ok or Bad. The better one is expressed.
  • Letters match the gene discs in game: D — Dung, L — Longevity, Y — Yield, F — Fertility, H — Hardiness. Disc colour is the copy: green Good, grey Ok, red Bad.
  • A young gets one random copy from its mother and one from its father — Mendel's peas.
  • Every animal carries two lineage markers; a young that gets two identical ones is inbred and its genes work at 0,5 strength.
  • In wild animals each copy is Good with 20% chance and Bad with 30%.
  • Cattle and sheep genes are shown on the animal's panel in game.
