question about triple gene morphs

Hi all. I have a question about morphs that involve three genes. Lets use the spinner blast morph for example. spider x pastel x pinstripe. how would you go about this. breed a pastel to a pinned then the offspring to a spider?

I guess what I'm trying to clarify is this...you combine 2 morphs and then breed it to the third?


Sorry for the newb question

theres a few ways, theres the cheap way like the way you described, the more expensive way, buy a bumble bee, or a lemon blast, or a spinner, and breed it to the last gene you want, EX: bumble bee to pin. or the most expensive way just buy one:gj:
all ways have there positives and negatives about them
1st way: cheapest initial cost, longest time need to devote the project, possible offspring you dont want
2nd way: more expensive, some time needed, possible offspring you dont want
3rd way: most expensive, no unwanted babies, no time need.

Thanks Tom !
