need tips on inbreeding

[Sensei Warrior]

Well I guess my first post should be in reply to someone else's first post. To me it all seems highly random. If you drop a princess on a royal that royal gets traits (I think I did it on accident once and over the next decade he went to inbred).

I'm playing the italians right now and my first heir had an inbred trait. Odd number of toes. I thought I could breed it out so over the course of the game I made sure the heir not only married another factions princess, but never the same faction twice. The lucky girls were from Sicily, Spain, France, England and the Byzantines. I have just hit the high era and what do you know my next heir to be has Odd number of toes.

Explain that one to me. You seem to be trying to do what I am trying not to do and neither of us is succeeding.

The inbreeding vices do not seem to be linked to actual inbreeding. I remember a poster who married all his Sicilian princes to their sisters without any noticable increase in the rate of inbreeding vices. There has long been the rumour that not marrying foreign princesses but daughters of local aristocrats increased the number of inbred vices but the developers denied this. However, inbreeding does seem to occur more often in certain royal lines, in particular the Egyptians and the Almohads.

If you seriously want to degenerate your royal line into a bunch of nine-toed, chinless morons, your best bet is to take a prince with a high inbred vice and make him king, select his most inbred son for the next throne and so on. And keep them out of battles: fighting decreases the rate at which some vices are acumulated (though I don't know if inbreeding is one of those vices).
