With Conclave DLC active, it is recommended to get the ambition Groom an Heir, which increases fertility by +20%. Or a willingness to advance children through your line of succession with disqualification or murder.Д®ven with two Genius parents, there is no guarantee that the offspring will be a Genius too, but if the player character raises several children, the odds of at least one of them getting this trait are moderately high ( ~66% in a scenario with two Genius parents and three sons born).ДЄ married couple's fertility decides the ability and likelihood of conception.Since genetic traits are random, breeding programs frequently require either: With that being said, some of the lesser negative traits (such as Clubfooted or Lisp ) can be somewhat useful for getting a few more points to use in the Ruler Designer, as typically about 85% of the born offspring are unaffected and it is usually possible to ensure that one of them becomes the heir(ess). If the player somehow ends up with one of them, it might be a good idea to (if possible) marry someone with a positive trait opposite in effect to it, as that will somewhat decrease the chance of the heirs having mediocre attributes and relations penalties because of it.

With a streak of bad luck, bad genetic traits could end up plaguing a dynasty for generations to come. On the other hand, negative genetic traits should be avoided when possible, unless the advantage cancels out the risk. With a little bit of luck they could end up staying in the family for a long time. As the positive traits are quite rare, the player is recommended to go out of their way to obtain them.
