In combination with the Dark budgerigar mutation the body feathers become deeper shades of blue. A blue budgerigar with a single Dark factor is called a Cobalt, and one with two Dark factors a Mauve. The World Budgerigar Organization has established precise standards for budgerigar body colours using the Pantone Codes, as shown to the right.
Unlike undersized cats of normal proportions (such as Toy and Teacup Persians), [6] dwarf cats suffer from a genetic mutation called pseudoachondroplasia (dwarfism without enlarged heads), a type of osteochondrodysplasia (bone and cartilage disorder). These genetic disorders of bone and cartilage are typically manifested as abnormal bone shape ...
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 ...

Mutations in this gene also cause white spotting. [9] Since a large variety of coat patterns exist within the various cat breeds, the cat is a qualified candidate animal to study the coat genetics of hair growth and coloration. [10] Several genes interact to produce cats' hair colors and coat

The SF Yellowface II Skyblue variety, described in Appearance above, is a composite of the Blue and Yellowface II mutations, having one allele of each. 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).
