Che colorazione sono?

To Tunde and Rachele and also all other interested:

Is exactely as Tunde said there are 3 sex-linked colours:

- s+ & S; this you read as s+ = gold and S = not gold (Silver)
- b+ & B; this you read as b+ = not barred and B = barred
- Choc+ & choc; this you read as Choc+ not chocolate and choc = chocolate.

The "+" refer to the original allel (from the Bankiva) where is NO "+" this refer to a mutation of the original allel (as the Bankiva had NOT).
When written with a Capital = (mostley) Dominant, when written with NO capital = recessive.

It is simple to see if a gene is sex-linked because the cocks have always 2 alleles of it
(s+/s+ or S/s+ or S/S)
(b+/b+ or B/b+ or B/B)
(Choc+/Choc+ or choc/Choc+ or choc/choc)
You can see cocks can be pure (2 the same alleles on one gene) and onpure (2 different alleles on one gene)

the hens have always one allel of it
(s+/- or S/-)
(b+/- or B/-)
(Choc+/- or choc/-)
You can see hens are always pure (no different alleles on one gene).

Look very good the way everything is written in because everything have is meaning.

The colour Blue is NOT a sex-linked colour. The way these alleles are writen are the same for males and females and than this is called "autosomale" (= for both sexes) :
bl+/bl+ = black;
Bl/bl+ = Blue;
BL/BL = Splash
Blue is a diluter of black (not of red).
Lavender is a diluter of black and red.
