Someone I know has a spider genetic stripe, the one I got Ivan from. Well since I offered to sell him back to her to make room for my new pastel (coming soon) she offered to trade me the spider genetic stripe for him and the pastel. She does not have papers but she's pretty darn sure that it's genetic. I will post pictures as soon as I am able. He has a stripe down 40% of his spine starting just past the head with two black lines (still got a bit of the spider squiggles) on either side all the way down but are straight from the start of his neck to after the first few inches. And the stripe is significantly lighter than the rest of his body. Basically is this a good trade? A male pastel poss het albino + reduced pattern normal male for a male spider genetic stripe? What is the chance that it's not genetic? She says if it shows it's more than likely genetic and at the least his babies will be highly reduced pattern.
