BEL question

Hello everyone, this is my first post here :P

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! :)

In general, lesser mojaves tend to be pretty white. There is a good chance it’ll develop a faint yellow stripe, though, as most seem to by the time they’re adults. While not as white as a super lesser/butter, you avoid the eye issues and still get a pretty darn white snake. I’m not sure if you’ve seen this already, but here are some photos of different stages of lesser mojaves: http://www.worldofballpythons.com/morphs/lesser-mojave/

Is that a sure thing? Because he told me it depends on the snake and he's produced some with amazing white stripes all over. I haven't seen a lesser mojave with white stripes so I'm unsure what he meant by that. Since the mom has a yellow stripe down her back, but the dad is also putting his genes in, how would that factor into it? Sorry if I'm asking obvious questions here, I'm very new to all this :)

Edit: I believe the dad is a leopard mojave

My female butter mojave pos. pastel, also has a slight yellow stripe, I think its pretty common for that kind of bel. Its hard to see but here is my girl, her stripe is very faint. Also included a pic of her as a hatchling, the stripe wasn't as visible when she was that small.https://uploads.tapatalk-cdn.com/201...b742483176.jpghttps://uploads.tapatalk-cdn.com/201...51a517052f.jpg

Over a decade in this hobby has shown me that most all BluEL combinations yellow out to some extent becoming less white and more cream and they also tend develop a visible dorsal stripe. The all-white Pied BluELs are stark white but you run into the microphthalmia problem with them.
