The Lutino Monk Parakeet (Myiopsitta monachus) is a color mutation of the normal-colored green monk parakeet. This mutation is caused by a lack of the pigment melanin, which results in the bird having a yellow or white plumage instead of the typical green. Lutino monk parakeets are often referred to as "yellow" or "albino" monks. The Lutino mutation is inherited as a sex-linked recessive trait, meaning that it is carried on the sex chromosomes and only expressed when two copies of the gene are present. In order to produce Lutino monk parakeets, breeders must breed two birds that are both carriers of the Lutino gene. When these birds are paired together, approximately 25% of the offspring will be Lutino. It's important to note that Lutino monk parakeets can have some health concerns such as an increased risk of sunburn and a higher chance of developing cataracts, which can lead to blindness. Therefore, a responsible breeder should take the necessary precautions to ensure that the birds are protected from the sun and are regularly checked by a avian veterinarian.
