@mw1525 thanks. I think it was one of the other two discussing about the single parent situation though. I was interested in whether the facial features skip a generation, or where I'd seen or heard of it, whether in this game iteration or in a mod.
One of my observations was about deceased generations who if their portrait is not in the family tree, they won't come out as a ghost or exist as a relative in the relationship panel. And if moving to another town, if they have the gravestone with them as well as the one's in between they will. Did I wonder if the genetics would be 'remembered' without it, or a memory of a living relative in the old town, I don't know. I do now. I think I remember seeing hair and eye colour operate like that regardless. I say remember because I'm still getting around to setting up a new Christmas break's worth of playing yet.
Its really good to hear there is history and they had been played. Why wouldn't they be eh, too much fun to be had to not.
My understanding is mods aren't created as brand new, but tweaked and modified off of existing game elements, large or small. So having seen things in nraas that play with the chances of grandparent's genetics and facial blending, as well as the thing that addresses the glitch - or maybe its not a glitch but intended! anyway, the thing where when the kid grows up they get a different face, or more or less blending or default or something ... anyway, that tells me that there is something in the game large or small, complex or not, that does facilitate facial features, as well as the obvious hair colours, skipping generations in a dominant/recessive manner, even though in CAS one founding sim might have been created with many tweaks to that feature to make it so original, and I guessed that it must assign the nose, chin whatever to one of the presets closest to it, to be able to then transport it through the genes as dominant or recessive. Perhaps customised one's get higher scores.
There's a neener, neener in there somewhere. Whomever fancies there is.
