Lutino cockatiel

Cockatiels use the ZW sex-determination system. In a simplified form, lutino is determined by a single recessive Z-linked allele. Male lutinos are of genotype ${\displaystyle Z^{b}/Z^{b}}$ , and female lutinos are of genotype ${\displaystyle Z^{b}/W}$ . A lutino male crossed with a wild-type female would result in lutino females and wild-type heterozygous males, as shown in the Punnett square.^[5]

All cockatiel colour genetic mutations have the same calls. The male lutino cockatiels can talk, sing, and dance (shakes head, makes the wings heart-shaped, etc.) to attract female cockatiels. Lutino cockatiels appear as full body in color yellow with two orange circular spots around the ear and cheek area.

The "albino" cockatiel also known as the whiteface lutino, is not the result of albinism. It is a breed that combines two genes of whiteface and lutino. The "Whiteface gene" removes all the yellow and orange that would be present in a Lutino, and the "Lutino gene" removes all the black and grey. So it has all white plumage, red eyes and pink feet.^[6] It is quite rare because of its all white plumage.^[7] The male and female of albino cannot be distinguished from their appearance, but need to be distinguished from their behavior or call.

The lutino-pearl cockatiel is a composite product of the lutino cockatiel and the pearl cockatiel. It has the appearance of a lutino cockatiel with yellow spots on its body.^[8][9]
