I've heard anecdotal results that a reduced pattern normal to a spider results in lower white spiders, but I don't know if that's true. I do know that my reduced patterned normal bred to a spider resulted in all reduced patterned babies. However, the spider was also reduced patterned.
Not sure if reduced pattern would affect the cinnamon or mojave, since those are both pattern morphs, and I would tend to believe that their pattern would be less likely to be affected by the normal. The reason I plan to pair my dark reduced pattern normal to my mojo this year is that I'd like to see if it will make the contrast between the yellows in the mojo and the darkness of the rest more extreme.
