I mostly leave my born in-game Sims genetics alone when they age up. However I do give them a different hairstyle, clothes and make-up. I've been exceedingly lucky with the way they age up, so far... The only exception is the chinless phenomenon that happens a lot in my game. I can't abide by that and always give them a chin.
There have been rare occasions when a nose job is needed or sometimes they age up with a weird body style such as skinny shoulders and a HUGE booty. I change those attributes with no remorse. I might leave the booty though, but tweak the shoulders so the proportions are more balanced.
The tagline is "You Rule" so that's my philosophy concerning genetics. I'm the Watcher, their Ruler and if I feel my babies are genetically challenged, it's my right to tweak them as I see fit! :)
Happy Simming! <3
EDIT: Tsk, I didn't swear but apparently the censor has a problem with the slang word for one's posterior. Guess in future posts I'll have to remember to give that word a boot, eh? No worries... ;)
