low grade cherry shrimp breeding

i just had a question about breeding. i recently red an ad for shrimp where someone culled their fire red cherry shrimp because they weren't as red as a fire red, basically saying they were high grade sakuras. they added that they carried the 'fire red genetics'. i was just wondering if the gene for the fire red works that way. for example breeding two fire red culls could possibly result in a fire red shrimp. if anyone has anymore insight on this please feel free to add.

Assuming that R is the PFR cull gene and r is the good bright gene
and ASSUMING that R is dominant
RR | Rr
rR | rr

In this case you have a 25% chance to get the color you want

so it all depends, it's possible but I don't know the specifics on which is dominant or not and I am sure there are other genes that help control

its all just selective breeding you breed your pfrs and get rid of the one that arent of pfr quality and eventually you will get a almost pure line

Even the finest PFRs occasionally produce an 'ugly' shrimp. I've got probably eight or nine different bloodlines that have been breeding for several years that still require constant culling.

Shrimp can have genetics for deeper colors even if they themselves do not express it.

Having said that, they will also throw a lighter color with higher odds. No biggie for the avg person keeping shrimp.

Ie. My DBVs throw a DBV light probibly less than 5% of the time. Although they have the darker color expressed, they can still throw dark colors. The ratio of throwing DBV lights from them is slightly higher, that's all. For most hobbiests this won't matter, because the number of darker colors will outnumber lighter colors and will combine to sustain a dark colony for quite some time.

As a selective breeder, culling constantly improves your strain quicker.
