Draft:Creamface cockatiel/Sandbox1

The Creamface cockatiel is a notable mutation in the cockatiel species, distinguished by its unique coloration. This mutation is part of the parblue series, which also includes the Whiteface and Pastelface mutations. All three mutations in this series influence the gene that controls the yellow pigmentation in a cockatiel's plumage, leading to variations in color.

Specifically, the Creamface mutation results in a significant reduction of the yellow and red pigments typically found in a cockatiel's plumage. Compared to the Pastelface, which also reduces these pigments but to a lesser degree, Creamface cockatiels exhibit an even more diminished presence of these colors. This leaves them with a very light, almost whitish face with only a hint of cream in the cheek patch. The overall effect is a bird that appears similar to the Whiteface cockatiel, which completely lacks yellow and red hues in its plumage.

The Creamface mutation is an autosomal recessive mutation. In terms of genetic dominance, it behaves co-dominantly towards the Whiteface gene. This means that Creamface and Whiteface mutations are alleles of the same gene and reside on the same set of chromosomes. When breeding different mutations, it's important to note that pairing Creamface with Whiteface can result in various offspring combinations depending on the genetics of the parents.

For instance, if a Creamface-Whiteface cockatiel is paired with a Whiteface, the offspring could be a mix of Creamface-Whiteface and Whiteface cockatiels. Moreover, pairing two Creamface-Whiteface cockatiels could potentially produce a clutch where half of the chicks are Creamface-Whiteface, a quarter are Whiteface, and a quarter are Creamface. However, it's important to note that the genetic outcomes in breeding can vary and are subject to the laws of inheritance and genetic variability.
