I am trying to find information about D&D's rules regarding ability-scores of a character who is a result of two other characters' reproduction. I haven't been able to find any official information on this subject (nor any unofficial information), but I presume that a child so created could have each ability-score selected in one of these methods:
- Rounded average of two corresponding parents' ability-scores (8 + 19 => 13 or 14)
- Either parent's ability-score, chosen randomly (8 + 19 => 8 or 19)
- Absolute value of one parent's ability-score subtracted from another one's (8 + 19 => 11)
- Just follow the same protocol as used when creating a character
Is there any official material on the preferred method, and, if not, which of the methods I listed are more preferable to use? Please keep in mind that I am looking for something that has at least a passing resemblance to real-world genetics.
I am trying to make a zero-player game that uses the rules of D&D 5E whereby each character has varying ability-scores, acts according to an algorithm, and can die from various causes. And since nobody likes a world where nothing happens, I need to add a mechanic to increase the population. I believe that if said mechanic acts close to real-life reproduction, the game will be more realistic. So what I meant by "preferable" means as close as possible to reality. Of course, I will eschew realism in favor of official formulae if said formulae exist.
