More on flock genetics… the Olive Eggers are a Crested Cream Legbar X Welsummer. I found the genetic break down for the CCL.
Crested Cream Legbar which should be the sire Z chromosome contribution to the mix…
Feathering: k+/k+ or k+/_W
Autosomal Red Genes
Red Bay Eye Color Genes
e+/e+, s+/s+, ig/ig, B/B or B/w
Yellow Skin w/w, Id/Id or Id/id
Cr/Cr (crest)
White Ear genes
O/O (blue egg)
Inhibitor for browning
(ig is gold inhibitor, ID is Dermal Melanin inhibitor)
Beak Yellow
Single Comb rrpp
So that is the potential genetic code of the roosters used to make my two Olive Eggers…
Welsummers taking a stab at their mother genetics the W side of the mix.
No Cr genes
white egg gene o/o
multiple browning genes
Yellow Skin w/w, Id/Id or Id/id, probably e+/e+
Red Bay Eye color genes
Red Earlobe genes
Feathering ?
There are variations Silver Duckwing, Gold Duckwing and Partridge. I think Partridge Autosomal Red is most likely. So s+
I think Partridge is 2 Brown genes, 2 Pattern Genes, and the gold gene (s+)… 2 gold in roosters, 1 in hens.
Beak Horn & Black
Single Comb rrpp
Okay that’s the start to figuring it out, so since hens are ZW and both girls look different… maybe something like this
Olive Egg = O/o & browning and browning inhibitors, but more browning genes so Olive color created.
I have not looked closely at their ears but they are probably part red and white
Single Comb rrpp
Both have a Crest so Cr/cr, Yellow skin so w/w, Id/Id or Id/id and ig/ig, Red Bay Eye genes, Yellow beak genes,
The big difference between Coratina and Catarina is feather pattern and color…
I think both are s+ on the Z chromosome, Autosomal Red, but in looking at the two parent breeds and comparing them Catarina definitely looks the most like a Crested Cream Legbar and Welsummer in pattern…
so probably e+/e+, s+, ig/?, B/w, Db (dark brown), a lacing gene Pg maybe, she posses patterning but is not very cream looking… it is possible her sire was a dark Legbar and was not ig/ig. Hatchery birds…
Now looking at her hatch sister Coratina the obvious difference is a lack of pattern… and a much lighter feather color so I think e+/e+, s+, ig/?, Br, no B or Pg at all so w/w, she may even posses Colombian genes Co… again big hatcheries breed in huge indoor facilities with multiple roosters and hens and as these are crosses they may be using lines that produce nice Olive Eggs but are not
necessarily closest to SOP… but that’s my thoughts on these two.
