The many color variations of budgerigars, such as albino, blue, cinnamon, Clearwinged, the various Fallows, Grey, Greygreen, Greywing, Lutino, Mauve, Olive, Opaline, Spangled, Suffused and Violet are the result of mutations that have occurred within specific genes. There are actually at least thirty-two known primary mutations established among ...
Early breeding results showed this Grey to be a Dark Grey (SF)/dilute, and Mrs Harrison went on to establish a substantial strain of Greys from this bird. [ 2 ] [ 3 ] In 1936, it was reported [ 4 ] that W F Shepherd of Kew, Victoria, also had Greys which he obtained from a colony breeder, and a Grey was also bred independently by R Hancock of ...
The correct identification and classification of the two quite distinct Greywing and Clearwing mutations was clearly understood by some Australian breeders by 1936, and probably considerably earlier, but the first article [6] to appear in Britain which clearly set out the genetic behaviour of the two mutations was written by R B Browne of ...
When pure-breeding (homozygous) Greywings are paired with pure-breeding Clearwings the resulting offspring, known as Full-bodied Greywings, are quite distinct in appearance from both parents. They have a body colour almost as deep as the corresponding normal variety and with the rich sheen of the Clearwing, but with medium grey markings ...

The Yellowface II budgerigar mutation is one of approximately 30 mutations affecting the colour of budgerigars. In combination with the Blue , Opaline and Clearwing mutations, the single factor Yellowface II mutation produces the variety called Rainbow.
Among the budgerigar fancy such a bird is said to be a Light Green split dilute, usually written Light Green/dilute, although Light Green/yellow has been used. [ 6 ] In a bird which has two Dilute alleles (the homozygote ) the number of melanin granules is greatly reduced, to around 5% of the normal amount.
The World Budgerigar Organisation has established precise standards for some budgerigar body colours using the Pantone Codes, as shown to the right for the Lutino. The Ino mutation also induces changes in the nestling. The down is white rather than grey and appears only sparsely, never growing down the centre of the back.
