The 'b' comes from splash (genetic code bb). Every gene has two versions, called alleles. Given traits must be inherited independently (their genes can not be located close to each other in the genetic material); External factors cannot influence the inheritance of a gene; and. R - Associated with poor fertilityin some homozygous breeds. Some common sex-linked traits are Cuckoo barring, gold, silver, slow feathering and dwarfism.

In order to account for the wide range of shades of brown eggs we see in our Sil-Go-Link line, there must be a relatively large number of eggshell colour modifying genes that are not yet known. The eye color calculator uses Mendelian genetics to calculate the probability of inheriting certain phenotypes (in this case, eye color) from parents. All these cockerels will appear silver because silver is dominant over gold, but they will have the gold colour hidden in there make-up.A gold cockerel mated to a silver hen, this time all the pullets will be gold as they only receive the gold gene from the cock bird, all the cockerels though will receive the gold gene from the cock and the silver gene from the hen, again this makes them impure silver cockerels an impure silver cock over a gold hen you would get both silver and gold pullets and cockerels because while the hen will contribute only gold to her sons, the cock will be dishing out both silver and gold to both his sons and daughters,remembering he is impure for silver means 50% of the time he donates a silver gene and the other 50% of the time he gives the gold gene. OHio ~ Come on Buckeyes, let me know your out there! They also are separated according to colour. Quail-like phenotype. This is brought about by the presence of the Muff Beard gene Mb.

They lump four hens and a cockerel and a cockerel into a breeding pen with little thought of what they are actually doing. It is an incompletely dominant gene. Breeding to a solid color silkie does not dilute the cuckoo pattern immediatly , however cuckoos can dilute over time. If you want to breed Silkies, I recommend studying the breed closer and when you decide on a variety, focus on it specifically.
