Sgenes & Mutations

Some arachnids have special genes (sgenes). Sgenes are passed down from the parents to the baby. If both parents have the same sgene, the baby will show the sgene.  If one parent has an sgene and the other doesn't, the baby has a 50% chance of showing the sgene. If the baby doesn't show an sgene, then it doesn't carry it, either.  Mutations are not passed down from parent to baby.  Got any ideas for new sgenes or mutations? Contact me at PI.
