Hi! I have been watching these topics and now I am curious...
I have a lutino male, turquoise male and a blue female. I know the parents of my turquoise were blue but I don't know any more.
My question is, what are the possibilities with either pairings, turqoise male/blue female or lutino male/blue female?
Thanks for your help!

Hi Gordie,
If your lutino male and your blue female aren't split for anything you get the following:
Males - 100% green split for blue and and ino
Females - 100% lutino split for blue
The turquoise and blue genes occupy the same allele on their chromosome (Jay, correct me if I'm wrong on this) and they both end up getting expressed visually. Again, if you assume neither of your birds are split for anything the offspring for a turquoise male and a blue female will be:
Males - 100% turquoise blue
Females - 100% turquoise blue
One final thing, though. Are you certain your turquoise male's parents were both simply blue? For blue birds, at least one of them would have to be visually turquoise in order to have any visually turquoise offspring.

Thanks Jim!
When I got my turquoise, he just had pins (got him in a trade and handfed him). I saw both parents and they were blue... I was a little bummed because I wanted a true blue but I am happy with what I got. I did show him to the breeder I got him from and she said that if she had known he was going to be turquoise she would not have traded. I did see the clutchmates too and they were all blue.

You’re right Jim. Turquoise and Blue are both alleles of the Blue-locus and behave co-dominant and hetero-allelic to each other meaning they will both be expressed.
A Turquoise specimen is homozygous meaning it carries two Turquoise genes, one on each chromosome. Some breeders sometimes refer to it as a Double-Factor Turquoise. A TurquoiseBlue on the other hand is heterozygous meaning a Blue allele is on one chromosome and a Turquoise allele is on the other.
Gordie’s IRN is most-likely TurquoiseBlue, just like at least one of the parents. The Turquoise mutation almost always comes with a baggage of secondary modifier genes. Because of this, Turquoise and TurquoiseBlues specimens are very variable in coloration ranging from almost Blue, combinations of Blue-Green-Turquoise, and an almost Green bird. This is the reason why it is not uncommon for people to mistake Turquoise specimens for Blues or Greens.
I would test breed the Blue hen to both males starting with whoever is more mature between the two cocks. After a few breeding seasons, you should be able to expose some hidden recessive genes especially sex-linked genes among the cocks.
Don't be bummed. Your TurquoiseBlue is more genetically versatile than a pure Blue. It can potentially throw both Blue and TurquoiseBlue babies. That's the reason why the breeder said she would not have traded had she known.
