My king is getting older, so I’ve begun preparing what I’d like my next king to look like - but I’ve got a few questions that I haven’t been able to find a clear answer on in what I’ve read so I figured I would try asking here!

First question - I saw somewhere that when you're retiring your king, there is a way to transfer his markings to the new king if you want to keep the old kings appearance. How does this work? Does it take the heir you choose and apply the same base, eyes, mane, etc. to the new heir? Or does it just apply the markings the last king had to the new heir? Would it erase the markings the new heir already has? Im very confused about the whole process, and cant quite find the answers to these in my research so far. If anyone could explain how this process works, I would greatly appreciate it.
I also saw someone said, it wouldn't transfer the fathers mutation. (Example - a Ferus) So if I wanted to transfer his looks and found a lion that was already a Ferus, would that work out? To essentially make the heir the same as how the father was, or is there a problem here that Im not recognizing?

Also! Another question I had - For an example, my king now has the marking Demonic Feralis, I have bred him countless times and also with lionesses with the marking as well. And in the results of all of his breedings he has only ever produced one cub with the marking. Ive started to wonder if it could be my fault that its not passing because of the marking slot I chose for it. I saw a thread talking about the mechanics of the fact that a marking has a better chance of passing if its the same slot on both male and female when breeding. And also something about conflicting marks in the same slot and the chances of each passing.
But what I’m wondering is - Is there any ideal slot to put a marking in to assure, or at least encourage it to pass along more than a different slot? For example - The marking in his first marking slot has passed countless times to his young, but I wouldn't want to put his best markings in slot 1 because they would inevitably be covered by all markings above it. If anyone has any advice on the manner, I would greatly appreciate it.

Thank you so much to anyone who takes the time to read this and respond <3
