Dominant: the allele that generates the phenotype in a heterozygous organism. The expected percentages of colours hatched will be affected by the sex of the birds mated together when birds carrying the sex-linked gene Silver (S) and its counterpart gold (s) are involved. At first, the results of these crosses may seem odd but if we think about the inheritance of sex-linked genes it makes sense. association model are far greater that the number of phenotypic records leading the well know large p, small n problem. 1.

Several colour varieties may be mated together and still produce birds with exhibition quality colour or colours which are close to the standard. The expected outcomes from mating these two colours together are listed below. <> For sex-linked barring, a Silver Crele bird is essentially a Dark bird which possesses a dominant, sex linked, gene called Barring (B). This is because the Silver and Gold genes are located on chromosomes which determine the sex of an individual, termed sex chromosomes.

For sex-linked barring, a Golden Crele bird is essentially a Partridge bird which possesses a dominant, sex linked, gene called Barring (B). Wildtype: allele(s) responsible for the ‘normal’ (non-mutant) phenotype. This is not always a certainty and sometimes Silver Laced males (hiding Gold) can appear to be a pure Silver Laced male.
