Cream face


CreamfaceMutation: Blue
Inheritance: Co-dominant recessive

 

The cream face is a color that isn't very widely known even though it has existed several years In 2009 I e-mailed to Mr. Jason Patin from Louisiana and asked about this color. Mr. Patin told me that the first creamfaces occured in South Africa to Mr. Lester De Kok. According to mr. Patin, Mrs. Margie Mason brought creamfaces to USA five or six years ago - about in 2003 or 2004.

The creamface is very beautiful color, where the mutation affects to yellow and red pigments. One could say it reminds some kind of in-between of the whiteface and the pastelface, since on the almost white facemask there's a very pale, tepid cheek patch. So the face is lighter than pastelface would have but still not as white as the whiteface has.

Some years ago creamface was still very rare but due to its' easy inheritance and genetical relationship with whiteface it has been spreading fast and reaching all the time stronger base. It is said that the color seems to be rather strong and healthy, but the problem at the moment is that careless "breeding" has resulted too much multi mutations and pure creamfaces are hard to find. Breeders should be aware of this and start to ennoble the color so that it wouldn't be a mix of a bit of everything. This can be easily done just by adding pure whitefaces or whiteface splits to the line.

Do not combine creamface with yellowface or yellowcheek. Also pastelface isn't wise since it dominates creamface. Keep in mind that if we ever want to combine for example creamface to dominant silver, the cf line should not carry lutino, cinnamon or other albinistic or dilution colors. (since they will ruin the dominant silver).

Gene behind the color: Parblue - Turquoisecreamface lutino

Creamface is an allele for whiteface. The whiteface color is caused by a gene called blue. Blue is responsible of the blue color of parrots and is autosomal recessive, meaning that the gene is needed from both of the parents. The gene doesn't actually cause the blue color itself, instead it removes other colors away so that blue coloration is left. To be more accurate, blue removes psittacine: yellow and blue. Thus, a green parrot would become blue and all the red, yellow and orange parts are left without pigment, and only white is left.

Whiteface also has sibling genes. These gene siblings that belong to the blue gene family but remove psittacine only partially, are called "parblue" - partial blue. If the parrot would be green, only part of the psittacine would disappear and the result would be more towards to blue - but still not purely cold blue. So the parblues are somewhere in the scale from blue to green. This is important to understand to also understand cockatiel colors. And, because cockatiels can't have the real blue color, the effect of parblue can be best seen from the yellow and red getting more pale.

Parblue colors are for example "aqua" and "turquoise". Aqua is a color where psittacine is resuced to 50%, turquoise has only around 20% psittacine left. So: pastelface is actually aqua and creamface is turquoise.

Like the blue gene, also parblues (pastelface, creamface, goldface) are autosomal recessives, but because they are each others alleles they have a bit different inheritance behavior towards each other. Most often a parblue dominates blue. So if there's one whiteface gene and one creamface gene, the creamface (that normally would be a split in this situation) becomes completely visible. Then again, creamface is recessive to pastelface.

With Whiteface:

- A whiteface can't be split to creamface (Whiteface needs two genes to become visible and after that there aren't any space in the locus for other alleles.)
- ...but a creamface can be split to whiteface (1 gene of wf, 1 gene of cf)
- A grey can be split to whiteface
- A grey can be split to creamface
- ...but a grey can't be split to both creamface and whiteface
(because then the creamface would be visible.)

With Pastelface:

- A creamface can't be split to pastelface (Creamface needs two genes to become visible and after that there aren't any space in the locus for other alleles.)
- ...but a pastelface can be split to creamface (1 gene of cf, 1 gene of pf)
- A grey can be split to creamface
- A grey can be split to pastelface
- ...but a grey can't be split to both pastelface and creamface
(because then the pastelface would be visible.)
