Anyone know how to breed yellow parrotlet??

[romancealex]

i have Green pacific parrotlets and Blue pacific parrotlets.
how to breed out a yellow colour parrotlet?:confused:

I have yet to figure this all out.

Breeding Color Mutations
So far, almost all the parrotlet mutations have been created in the Pacific parrotlets. There are a few mutations in the other species such as pied Spectacles, cinnamon and possibly dilute Green Rumps and blue Blue Wings but mainly it is the Pacifics that have the most diversity of colors. Also, all but one are recessive, non-sex linked mutations. Currently, there are blue, American yellow, fallow, cinnamon, lutino, pastel, gray green, American white, silver, gray, recessive pied, dominant pied, albino and combinations such as fallow-blue, pastel-blue and cinnamon blue. Understanding recessive single mutations, using blue, is as follows:

bb x bb = 100% Blue Offspring
bb x bG = 50% Blue & 50% Blue Split Offspring
bb x GG = 100% Split to Blue Offspring
bG x bG = 25% Blue, 25% Normal & 50% Split to Blue Offspring


GG = Normal Green
bb = Visual Blue
bG = Split to Blue


In order to produce comination mutations such as dilute-blue (formerly "American white"), albino and fallow-blue, pastel-blue and cinnamon-blue, it takes at least two generations. In order to produce dilute-blue, you need a dilute and blue pairing the first generation. The second, must be an dilute/blue split pair, paired with unrelated dilute/blue splits. This would produce the following percentage of mutations:
6.25 % GG
12.50% bg
12.50% dG
25.00% Gdbb-d
6.25% bb
12.50% bb-d
12.50% db-d
6.25%dd
6.25% b-db-d


GG = Normal Green
bb – Visual Blue
dd = Visual Dilute
b-db-d = Visual Blue-Dilute
bG = Blue Split
dG = Dilute Split
bb-d = Blue Split to Blue-Dilute
db-d = Dilute Split to Blue-Dilute
Gdbb-d = Green Split to Dilute, Blue and blue-dilute

You cannot breed an American Yellow from the colours you have on hand, unless your greens happen to both be split to yellow (there is no way to know this unless you know your bird's genetic history, as "split to" a colour still leaves the bird visually green).

Best practice indicates that to avoid unknown splits in your clutches, you should breed a genetically green-split-to-yellow to a visually yellow bird. The resulting offspring will be 50% visually yellow and 50% green-split-to-yellow, with no unknowns.

So does that make yellow an autosomal recessive trait, like blue? Just curious.
If so, what happens when you breed blues to yellows?

how to breed genetically green-split-to-yellow??
using both green??

Thanks for helping:)

Sara-
That's correct. Breeding a blue to a yellow will result in a visually green bird that is double split to both blue and yellow.


Alex-
It's a bit more complicated that it seems. Visually green birds can be what we call "clean greens" (no genetic history of being split to any other colour for at least three previous generations) or they can be green split to blue or green split to yellow or green double split to both blue and yellow. It is impossible to tell by looking at a green bird whether it is a clean green or carries unknown splits - this is why it is important to get breeder birds from other breeders who keep good records, because with a pet shop bird who simply appears visually green, there is no way to know what else it may carry genetically.

To get a green-split-to-yellow bird, you would pair a genetically "clean green" with a visual yellow. All resulting offspring will be green-split-to-yellow.
