Does a English White × Rosetta pairing breed true?

No. This pairing segregates — you will get 2 different outcomes in the same hatch, in the proportions listed on this page.

English White × Rosetta: What Color Chicks Do You Get?

This pairing gives you 50% Tuxedo-type Pharaoh and 50% Tuxedo-type Rosetta.

The hatch, chick by chick

Chick looks like	Carries, but does not show	Egg shell (hens)	Share of hatch
Tuxedo-type Pharaoh	—	Normal	50%
Tuxedo-type Rosetta	—	Normal	50%

Tuxedo-type Pharaoh: A single dose of white spotting shows as partial white — bibs, belly patches, odd white primaries. How much white it puts on a bird varies a great deal, so expect a spread rather than a matched set.

The Punnett square

Extended Brown

	E	e+
e+	E/e+	e+/e+
e+	E/e+	e+/e+

Extended Brown: Incompletely dominant. Two copies make a Tibetan, one copy makes a Rosetta, and no copies leaves the wild Pharaoh base — which is why a Rosetta pen can never breed true.

What each parent brings

English White

Two doses of white spotting. White × white breeds white reliably; crossed to anything else it hands every chick a single dose, which is where tuxedo-patterned birds come from.

Built on recessive white spotting: two copies produce the mostly-white bird. Because the gene masks whatever color lies beneath, English White × colored crosses can throw surprises in later generations as hidden colors resurface. White × white breeds white reliably.

Rosetta

Extended Brown heterozygote (E/e+). One dark gene, one wild-type — which is why no Rosetta pen breeds true.

Rosetta is Extended Brown heterozygous (E/e+). Because they carry one dark gene and one wild-type, Rosetta × Rosetta splits roughly 25% Tibetan / 50% Rosetta / 25% Pharaoh — you can never have a pure-breeding Rosetta pen, and every hatch is a surprise assortment. Tibetan × Pharaoh makes 100% Rosettas if you want a whole covey of them.

What this assumes

Both parents are exactly what they are sold as. A bird carrying a hidden recessive — roux, celadon, white spotting — changes these numbers. Recessive carriers are invisible, which is the whole reason surprises happen.
These are per-chick probabilities, not a quota. A 50/50 split does not mean half your hatch of ten will be each. Small hatches swing hard; the ratios show up over dozens of chicks, not eight.
Coturnix inheritance is debated and varies by line. The modes used here are the ones consistently reported by breeders, and they match what our own variety guide says — but verify against your own stock before you plan a season around it.
Color only. Size, lay rate and temperament come from line selection, not from these genes.

Stop guessing which bird carries what

Quail Keeper Max stores every bird's variety and celadon status, builds 4-generation pedigrees, and predicts the hatch from your actual pairings — so the invisible carriers in your covey stop being invisible.
