I have a ch genetic girl that I bred this year to a pastel and one baby is a reduced pastel. I hatched only females so I cant breed back to mom (yet)to see if she what happens. Lots of people like to breed reduced patterns to spiders to get a more reduced girl. Jon's hunter's guide gives some great info.

Here is a pic of my reduced girl Raquel.
