The science of budgerigar color genetics deals with the heredity of mutations which cause color variation in the feathers of the species known scientifically as Melopsittacus undulatus. Birds of this species are commonly known by the terms 'budgerigar', or informally just 'budgie'.
When combined with the Dark mutation the body colour of both Greys and Grey-Greens becomes slightly darker, but the effect is much smaller than the effect of the Dark mutation on Light Greens and Skyblues. As this is a dominant mutation the colour changes described above apply to both single factor (SF) and double factor (DF) Greys and Grey-Greens.
The loci of the Dark budgerigar mutation and the Blue allelic series are situated on the same autosome, so the Dark mutation is linked to the Blue allelic series (see genetic linkage). The cross-over value (COV) or recombination frequency between the Dark and Blue loci is commonly stated to be about 14%, [ 8 ] but some experiments have found ...
The Greywing is an autosomal mutation of the dil locus with the symbol dil gw, and so is a member of the multiple allelic series which also includes the Dilute (dil d) and Clearwing (dil cw) mutations. [8] The Greywing allele is recessive to the wild-type, dominant over the Dilute allele and co-dominant with the Clearwing allele.

The history of the English Grey begins in 1933, when Mr T Watson of Bedford, England, discovered and purchased a hen of a slatey grey colour from a dealer.This may or may not have been an English Grey, as Mr Watson failed to establish the strain, but his report in 1935 [3] of the bird's existence prompted both Mr E W Brooks of Mitcham, Surrey to report his breeding of Greys from two Cobalts in ...
Exhibition style "budgie" (left), as compared to pet-type budgerigars. The budgerigar has been bred in captivity since the 1850s. Breeders have worked to produce a variety of colour, pattern and feather mutations, including albino, blue, cinnamon-ino (lacewing), clearwing, crested, dark, greywing, opaline, pieds, spangled, dilute (suffused) and ...
Although the Blue mutation was first seen soon after the first Dilutes, in 1878, and had become established by 1890 in Europe, the first combination of the Blue and Dilute mutations in double homozygous form did not appear until around 1920, some 30 to 40 years later. This combination was the White (known as Silver in Australia), and it was ...
