It depends on how you look at it. No matter how many genes you have in addition to the Pinstripe, it will always be a 1 in 2 chance of the offspring getting the Pinstripe gene and a 1 in 2 chance of the offspring getting the Mojave gene. So if you were to pick a Lemon Blast, you would have
a 1 in 8 chance of producing a normal
a 1 in 8 chance of producing a Jigsaw Blast
a 1 in 4 chance of producing a Lemon Blast
a 1 in 4 chance of producing a Pastave
a 1 in 4 chance of producing a Jigsaw
a 1 in 2 chance of producing a Pastel
a 1 in 2 chance of producing a Mojave
a 1 in 2 chance of producing a Pinstripe
But mathmaticaly speaking, a Pastave, a Lemon Blast, and a Jigsaw Blast are all subsets of the 1 in 2 chance of producing a Pastel. So it means that while you have a 1 in 4 chance of producing a Jigsaw, half of those Jigsaws have a chance at being Jigsaw Blasts. So you still have the same odds of producing a Jigsaw, but you could also produce a more complicated snake.
If you picked a Pinstripe Hypo, your odds would still be a 1 in 4 chance of producing a Jigsaw, but because the Pinstripe Hypo is homozygous for Hypo, all the babies would be heterozygous (het) for Hypo. So they would have 1 Hypo gene, but it would not affect their appearance.
