How do genetics work?

[Chicks n stuff]

Pattern genes/genes that react with pattern genes:

Co(Columbia)- autosomal, dominant gene.

Db(darkbrown/black tail)- autosomal, dominant gene.

Ml(melanotic/melanised)- autosomal, dominant gene.

Pg(pattern gene)- autosomal, dominant gene.

The resulting pattern will differ depending on what foundation color your chicken is.

Spangled: (Db+Ml+Pg).

Laced: (Co+Ml+Pg), or (Co+Db+Ml+Pg).

Autosomal barring/black barring: (Db+Pg), autosomal barring will only show up on roosters that are ER(birchen).

wow you know a lot!!!
that's a lot to take in

Trait:



M(multiple spurs)- autosomal, dominant.



Po(Extra toes/polydactyl)- autosomal, incomplete dominant, expressivity and penetrance extremely irregular.



0(Blue egger)- autosomal, dominant.



br(brown eyes)-sexlinked, recessive.



Comb:



bd(Breda comb/Combless)-autosomal, recessive.



DV(V-shape Duplex comb)- autosomal, incomplete dominant.



DB(Buttercup, Duplex comb)- autosomal, incomplete dominant.



R(Rose-comb)- autosomal, dominant.





P(Pea-comb) - autosomal, incomplete dominant.



R+P(Walnut-comb)- both autosomal, both dominant.



Feathers:



h(Silky)- autosomal, recessive.



F(Frizzle) autosomal, dominant, semilethal.



Na(Naked neck)- autosomal, dominant.



K(late/slow feathering)- sexlinked, dominant.

https://pubmed.ncbi.nlm.nih.gov/2837753/





k+(rapid/fast feathering)- sexlinked, recessive.



Hf(Henny feathered)- autosomal, incomplete dominant, sex-limited.



Pti(Featherfooted)- Autosomal dominant with multifactonal

modifiers (possibly 2 or 3 loci).



v(Vulture hocks/longer leg feathers at the elbow of the leg)- autosomal, recessive.



Mb(Beard)- Autosomal, incomplete dominant, incomplete penetrance.



Cr(Crest)- autosomal, incomplete dominant.



Wc(white crest)-autosomal, incomplete dominant.



Lf(LONG FLOPLUMES)- autosomal, dominant.



mt(non-molt/long tail)- recessive.



Gt(NON-LIMITED GROWTH/long tail)- dominant.



Et(Eartufts) - autosomal, dominant, incomplete penetrance

and irregular expressivity, lethal?



Rp(Rumpless)- autosomal, dominant, lethal?



Skin/Leg:



Fm(Fibromelanosis/dark skinned/dark shanked)- autosomal, dominant, with multifactorial modifiers. As seen in silkies.



w(Yellow-skin/willow-green-shanked)- autosomal, recessive. Willow green like you can see on Easter eggers.



W+(white skin/white-shanked)- autosomal, dominant.



y(sexlinked/white-skinned/white-shanked)- sexlinked, recessive.



Id(dermal melanin inhibitor/ Light/white-shanked)- sexlinked, dominant.



id+(dermal melanin/slaty blue-shanked)- sexlinked, recessive.



W+ + id+(slaty-blue-shank)- (W+autosomal), (id+sexlinked),(W+dominant), (id+recessive).

7. es(speckled), I found a description, for this foundation color. Described as "speckled head (blurred head)",
"The sixth allele at the E series plumage-pattern locus. Chicks show confused speckled-blurred head pattern. Their back strips tend to be less precise than the
"wild-type" chick (item 452) and the ground-color is dusky. Adult males have the "wild-type," e+/e+ coloration. Adult females are very coarsely stippled." (Page 34, item 454).

Just for clarification there were only eight primary color pattern/foundation colors in the "international registry of poultry genetic stocks," which is why es(speckled) comes in as number six in their E series.
