Cross breeding for colours

As @shrimpsilkies said, it depends, if the Fee gene is homozygous or heterozygous, the brown/reddish can be more pronounced on hets.

This roo here is hom Fee factor:

A falb fee is just a wild/pharaoh type bird with one or two copies of the fee gene, which makes the red/brown gray scale. In Italian/fawn it makes the bird white with black spots (called pearl) and in Rosetta/EB it makes a usually brownish bird gray or even almost black (called Grau or Grau fee). Homozygous birds tend to be more black/white/gray than heterozygous birds. Then you toss in the roux gene which makes the blacks red and it really gets interesting: I’ve got an Italian base bird that is overall white so a pearl or fee carrier but also all the spots and stripes are red meaning it Carries roux too. It might also be tuxedo (white breast so can’t easily feather sex with breast spots) but in an Italian the male often has a chestnut head (except fee and roux are in there messing that up!). I thought it was male with the red stripes and limited spots but now see some light spotting and a double stripe even if it is red (roux!) so female? Then you throw in pansy, sparkly, silver…and it really gets confusing! But you can get some cool birds!
 
Your “pharaoh with Italian” on the bottom row there is a Falb Fee and cannot pass on any Italian color.
If you want pure Italian, crossing your Manchurian male to the two pharaoh hens will give you largely gold offspring, although they might be Manchurian, some may have speckles like the Italian.
Your “pure Tibetan” is a Rosetta, which is with one gene for Tibetan and one gene for Pharoah. Using the Falb Fee roo will get you 1/2 Fees (gray, no brown pigment) and 1/2 normals (brown pigment). 1/2 of the normals will be Pharaoh and 1/2 will be Rosetta. Crossing Rosetta to Rosetta will get you 1/4 Tibetan. The Tux is pure Tibetan but Tux can be hard to breed out if you want pure Tibetan.
I don’t know what any of the Golds (Manchurian, Italian) look like when crossed to Tibetan or Rosetta.
Hi there first post here but I'm trying to get to grips with colour genetics… I have a roo pharaoh, pharaoh hen and a rosetta hen
Set up ready to breed. P+Pim expecting pharaoh but what will I get from P+R will I get a 50/50 mix in the clutch of will the extra pharaoh gene know out the rosettes as I understand Tibetan and pharaoh make rosseta, also hello from the uk :)

Hey first post, uk guy here, Ibe got a breeding set up that includes one pharaoh roo one pharaoh hen and one rosetta hen,
I understand P+P=P
But what should I expect from P+R, as Rosetta is formed from Tibetan and pharaoh

My golds are all set up with one Manchurian roo & hen and one Italian sparkly hen so Im pretty sure that's going to be all, locus Y and all gold chicks but varying patterns from of the two hens.

And have a set -up with a wild-type Pharaoh roo, wild-type Pharaoh hen and one Rosetta hen, I'm assuming that WP+WP will give back wild-type Pharaoh offspring.

However, I can't seem to work out what my WP+R will produce in terms of colour ways.

I understand that wild-type Pharaoh x Tibetan = Rosetta

But will that mean further dilution of the Tibetan gene or a 50/50 colour spilt in that clutch of wild-type Pharaoh & Rosseta

because now I'm wondering if I should just make two different trios wild-type Pharaoh and get the Rossetta a Rossetta roo and sister wife :)
Hello from the UK this is my first time posting here, I know this is an older thread but hoping its still live or I can reactivate it somehow ha
