Partridge x self blue silkie = ? &

[melissa508]

Im curious as to what you get from a partridge silkie roo x self blue female...pictures would be great.

Also, does self blue dilute like andalusion ?

I could be wrong, but I think you get all black. I don't know about the dilution.

It doesn't dilute "like " Andalusian Blue, but it does dilute Black to lavender (self blue) and Gold to buff or light straw color, ( Andalusian Blue only dilutes black)

So in the F1 cross of the Lav on Partridge, you would get all black offspring that would most likely have gold leakage and they would be Split Lavender ( carrying only on copy of the lav gene.

Then when you cross the F1s together, you can get more Blacks, Lavenders, Partidge, and Partridge Isabel ( lavender diluted partridge)

First generation would likely be partridge--it depends though on the E-allele carried by the self-blue (lavender). Penciling would not be complete as for a bird with two copies of the pattern gene. If the lavender is E or E^R, the offspring would likely be black. Bred back to lavender, half would be lavender. Depending on the e-allele (as mentioned earlier, some could be lavender partridge--but as mentioned above, pattern quality with one copy of Pg would be less than on a biord with two copies. If the F1s are bred together, a percentage would inherit two copies of lavender as well as two copies of Pg.

No. Andalusian blue dilutes only black pigment, and one copy dilutes to blue; two copies dilute to splash. Lavender dilutes both black and red pigment, and two copies must be present for it to have any affect.​

So could the Partridge dilute to Grey?

 

[Sonoran Silkies]

Genetically the only difference between partridge and grey is the silver gene. Partridges are gold; greys are silver.

ok, but if the Partridge is splitlav,then bred to lav, could the lav cause a grey. That is what I was reading into the other postring.

No. It would look very different. Grey (silver gene) replaces gold with silver--there is no red/gold in the bird. Lavender in one dose has no affect on appearance. If a partridge is split for lav, when crossed with a lavender you would end up with 50% lavender partridges (let's ignore penciling quality for now). In these birds black is diluted to lavender, red/gold is diluted to isabel. There is a photo of one in Genetics of Chicken Colours. VERY pretty bird. The colours are those of a true porcelain, but the pattern is that of partridge.​

Well don't have the book, is there a picture on line somewhere?
