Penciling is part of certain patterns: partridge and grey. An S/s+ split would not be appropriate for either of these colours as it is incorrect for both. Females cannot be split for silver: they are either silver or gold as they only have one copy of the gene.
Promise...last question!
I am sorry, I think I have myself confused. I think I am good on the penciling but the silver split in the males has me a bit confused. When you say they are silver split for males, does it mean they carry two copies of the silver gene? Or is it they are a blue partridge for the color, but a recessive silver gene? And I shouldn't breed a silver female to a silver male for best color?
I think I will really need to dig in and research color genetics now that I am getting more into the silkies
Is there a place I can check out or something I could buy to learn more about color genetics and what would be appropriate colors to breed?
Thanks for helping me to be less confused which can be a hard task at times! LOL
When a gene is referred to as being split, it means that the bird carries two different alleles for the gene. In this case, one copy of silver and one of gold (the gene is named silver, the alleles for that gene are named silver (the incompletely dominant allele) and gold (the recessive allele). There are also a couple of fairly rare alleles for this gene.
The genetic recipe for partridge is e^b/e^b s+/s+ Pg/Pg. For a female it is the same, except that a female would have s+/- as she can only have one copy of this gene. If you add blue (Bl/bl), you will have blue partidge. To know if that is what your birds are, I would really need better photos with accurate colour. They
could be greys with autosomal red, but in that case, the males would appear to be henny feathered.
