Hello everyone, this is my first post here

I'm buying a lesser mojave from a breeder and he said there's lots of variability in how they can turn out. However, he also said that it'll probably look like the mother (also a BEL) does (with a light yellow stripe on the back). All this has made me a bit confused on what the snake will actually look like as it grows up, lol. I figured I'd ask here. Thank you in advance!
