RE: [Genetics-Psittacine] turquoise parrotlets
- Turquoise alone is recessive; You need two turquoise parents (one may be a
carrier) to get a baby turquoise.
But, since Turquoise do not have its own locus (place), it uses the locus of
the Blue. Thus, when Blue is present with Turquoise, both mutations have to
share the same locus, and the Turquoise can be considered as co-dominant
with blue: One allele Turquoise and one allele Blue.
In your specific case, pairing a Turquoise and a Blue parrotlet you will get
Turquoise-and-Blue parrotlets, referred to as TurquoiseBlue.
The possible allele combinations are:
-Green and Turquoise: a green parrotlet, split to turquoise.
-Turquoise and turquoise: a homozygous Turquoise parrotlet.
-Turquoise and blue: a heterozygous TurquoiseBlue parrotlet (written with
both names together, to indicate co-dominance).
1- Pairing a Turquoise to a Turquoise:
100% Turquoise babies.
2- Pairing a Green to a Turquoise:
3- Pairing a Green to a TurquoiseBlue:
4- Pairing a Green to a Green/Turquoise
5- Pairing a Green/Turquoise to a Green/Turquoise:
50% Green/Turquoise babies,
6- Pairing a Green/Turquoise to a TurquoiseBlue:
7- Pairing a green/turquoise with a blue:
8- Pairing a Green/Turquoise to a Turquoise
9- Pairing a Turquoise to a Blue:
10- Pairing a TurquoiseBlue to a TurquoiseBlue:
11- Pairing a Turquoise to a TurquoiseBlue:
Pairings 3, 4, 5, and 6 should be avoided as it will be impossible to
identify the genetics of the green baby birds without test-mating them.
The Turquoise mutation may be combined with any other mutations. Example:
American Yellow Turquoise
American White Turquoise
Pied Turquoise, and etc.
As an exception, the Lutino Turquoise is visually pure Lutino; Turquoise
will be hidden, even though it is there and it is transmissible to the

Can anyone tell me if turquoise is dominant or recessive in parrotlets? If I
pair a turquoise to blue bird, will any of their offspring be turquoise?

No problem, man.
I learned all this here; this site is a life-saver.

Awersome! Thank you so much. That's the best explanation on turquoise parrotlets ever. I searched high and low, and tried to figure it out myself on gencalc, but the mutation is so new, I couldn't find any info. Thanks again.
