yup, so then we are calling "panda" double pied (PiPi).

recessive white wild type bird with 2 "Pi" recessive alleles

blueprint of bird above would probably be= whwh Br⁺Br⁺ yw⁺yw⁺ e⁺e⁺ PiPi

whwh- 2 recessive alleles= white instead of Wh+Wh+ (wildtype)

and

PiPi- double- pied (panda), again 2 recessive alleles instead of pi+pi+ (wildtype)

now, back to Syble's birds.

#1 is definitely Pipi+

I do wonder about the other 3...

a test cross with a solid bird would prolly yield the answers... so yes, I would keep #1 and #3

It also depends on what the bird carries as well. Coturnix carry many genes that the calculator is not accurate. That's why a white pops out of wilds after 5 generations. Epigenes too play a role. We would need the parents and their blue prints in order to figure out how to make the tuxedo pattern definitive.

#1 imho, I think the reason whites pop up in brown pens is because the breeder is using splits in their pens... which can look brown but carry recessive white, when 2 of these splits meet up split roo x split hen, there is a 25% chance of white offspring, breeders should be testing their browns against white birds, if a brown bird crossed with a white bird produces whites then the original brown bird is a "split" bird carrying one copy of the recessive white gene (but is still visually brown). I know this because I crossed my browns with my whites and back to each other and I breed white split birds.

#2 "So my question is this, how long does it take for any previous matings to clear out before any hatchlings will be true?"- I learned a neat trick from someone, you take the amount of days in the incubation period of the species, 17 days for quail, that hen can be fertile with a roo after mating for ~17 days. Chickens ~21 days, ducks, turkeys, etc., also... split those times in in half, ~8 days for Quail, that is how long the egg is at peak hatchability, after that it decreases, same with chickens, etc. just a general rule of thumb...

Birds can contain the sperm for up to a month at times so I would give at least 2 weeks before incubating a new project to get maximum results.

The fun thing about coturnix is that they are so fast reproducing, we get so many neat color combos so we can test theories out. My lab is full of neat projects. I do have some split white to brown birds so I know which carry what in my pens but coturnix are so jumbled in genetics at times, Most colors do breed true over 5-6 generations. Can test cross to see what they carry as well. Breeders do this all the time, even to create new colors. 

Syble you are correct in your statement.

Solids, as in all white, can carry pied. They are carriers of many colors usually. 

I would breed tuxedos to tuxedos and see how how your offspring turn out. The best combination in a pen is Tuxedos, whites, and pieds anyways.
