Colour genes question

[ReeceLawrence]

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 the two hens.

I understand that wild-type Pharaoh x Tibetan = Rosetta
And have a set -up with 1 wild-type Pharaoh roo ,who's giving Egyptian colour locus Br ,1 wild-type Pharaoh hen whos atm not giving off any red or brown so could be Flab fee but lets just say for now she's just a bit of an ashy WP, 1 Rosetta hen locus E

I'm assuming that normal WP+WP will give back wild-type Pharaoh offspring.

BUT how Will the Br effect the E if my suspicious are true and what will locus Br and flab fee effect be if I am again correct?

Will that mean further dilution of the locus E or will (lets for arguments sake say he's not Br just )WP ,inherited the extra locus E gene back and give me some rosettas..or will it be Ee and give me Tibetans because of POTENTIAL Br +E

…because now I'm wondering if I should just make three different trios up golds to golds ,wild-type Pharaoh and get the Rossetta a Rossetta roo and sister wife

Ideally I'd like to create a golds-locus Y and Rosetta-locus E combination after which is why I'm don't want to further dilute the locus E gene

Any guidance is greatly appreciated. Reece

PS Hello I'm 35-year-old neurospicy from the UK, this is my first time posting here my brain is literally spinning out over this colour Genesis , I bred white apricot and mallard colored call ducks as a boy and kept button, Japanese, Californian quail as a teen, I've got back int it all last year when I realised no one can tell no anymore ,, I got this lot in specifically for selective breeding, they are all so chill and tame with gorgeous colour, I'm also going to gain 2 trios of calis to breed shortly ,if I'm honest they are my favourite ,its the little head plumage on the male that's does it for me ,I'm on the hunt for Mearns but they are like gold dust here in the uk I'm also in pursuit atm of some chakurs if the dude ever replies lol which will be my 1st go at breeding partridges.

Egyptian would be a pharaoh carrying roux, roux is a sex linked recessive, hens carry and express one gene and cannot pass it to daughters, males can carry one or two genes but only express with two, a homozygous male will pass it to all his daughters, meaning you can tell which are female at hatch if the hens are not carriers. Roux makes your bird overall red, no matter the base color, Egyptian in pharaoh, autumn amber in Italian, and scarlet in Rosetta. Fee turns your bird black, white and grayscale and is expressed even in heterozygous form but is strongest in homozygous, falb fee in pharaoh, pearl in Italian, and Grau in Rosetta. They can also carry and express both genes plus the base color (autumn amber fee for instance).
