S - This gene is called 'silver'. Extended black, hackle, shoulder and saddle of the males may leak groundcolor (eg red) depending on unknown absent genes. One of a number of possible alternative forms of genetic information at a gene locus . The blue eggshell pigment, oocyanin, is a by-product of bile formation and is present throughout the eggshell.The eggshell colour genes interact in the following way. Glossary and definition of terms used with poultry breeding: How to breed for a trait for sexing day-old chicks: causes yolks to be lighter in colour and reduces xanthophyll levels in blood plasma.

I thought about buying some hatching eggs from her at some point but don't know how to tell the difference between gray and blue Silkies. For the purposes of this discussion, I use the fictitious symbol, Br, to indicate a brown eggshell colour gene. Fill the first column and row with the parent's alleles. A bird that has two genes for a given trait is homozygous for that trait.The genotype is the actual set of genes. The lavender color does not exist naturally in Silkies and must be introduced by another breed. The Partridge Silkie is a difficult variation to perfect, however. I believe there are some people working on red silkies in Australia. In the case of laced varieties, such as the beautiful Gold and Silver Laced Wyandottes, weare sometimes forcedto adopt the double mating principles.Double mating requires setting up a cockerel-breeding pen and a pullet-breeding pen. Fowls usually have tails. Brown eggshell colour is a complex trait and as many as 13 genes have been proposed to account for the range in eggshell colour.

In this case, the inside surface of the eggshell will be significantly less green and more blue than the outside surface, which is where most of the brown pigment is.Since the blue and brown eggshell colour genes should be at different locations, we need at least two pairs of genes to describe the genotypes of the blue, white, green and brown layers. For example, a bird that is heterozygous (has one gene instead of two) for a given dominant trait may look the same as, or similar to, one that is homozygous (has two genes) for that trait.They both have the same appearance or phenotype. BANTAM eb/eb s+/s+ Pg/Pg Mh/Mh Db/Db or Db/db+ and recessive black, STANDARD eWh/eWh Pg/pg+ or pg+/pg+ Mh/Mh Db/Db and recessive black. Like how do you get blue, splash, mottled, or cuckoo colors? Lack of frizzle. Dec 18, 2012. Each gene comes in two versions called alleles. lav - Recessive. It is difficult to breed the black out of buffs, so only buff varieties should be bred together to achieve the breed standard.

A small amount of this pigment is present in all hair colors. Multiple alleles have been proposed. This is brought about by the presence of the Muff Beard gene Mb. Her chicks are sex-linked chipmunks with dark legs. Silkie genetics work like all other poultry colour genetics. I have read over some stuff I found online I will share with you.

The article at BrownEggBlueEgg.com by Dr. W. F. Hollander Silkie Genetics lists several of the Silkie breed's genes. There is no barring gene on the W chromosome so females can have only one. Two nigrum genes, E, and one Bl gives a blue chicken; two Bl genes gives splash. Larger black spots are more desirable than small ones. My understanding at present is that the locations of the brown eggshell genes are not known and it is not known how many brown modifying genes there are or where they are in relationship to the genes of known locations. For example, lets consider a cross between a bird that has two frizzle genes, homozygous for frizzle, (F, F) and one that is without frizzle, (f+, f+). EYES, EARS AND SKIN There is very little known on the genetics of silkie eye colour. When feathercolor of the whole bird is reserved for at most one pigment kind, pheomelanin or eumelanin or none.
