the genetics question

[swanwillow]

Okay... I'm looking at pictures, and trying to figure this all out. TRYING to is the key here.

right now, I'm stuck on the INO gene. Not the green is lut, blue is cream, and albino. got that part down (or is creamino something else, see, second guessing myself! cause blue is albino... creamino turq? BAH!)

Okay, ANYWHO... the ino gene. I know it can mask things, but doesn't it also WORK with things, as in the pallid-ino's.

How does the INO gene work, and are there advantages to having it in a breeding line? I know that there are disadvantages, since it can mask other things (piedness)

[Jay]

The Ino gene serves one purpose. It removes melanin (but not completely since melanin is essential in other organs needed to sustain life).

Ino will mask black melanin (aka eumelanin) dependent mutations such as Grey, Blue, Violet, Cobalt, Pied, etc. But Ino is not very effective with removing Brown melanin hence combination of Ino and Cinnamon can produce visual Lacewings (Cinnamon-Inos).

Inos can combine well with certain mutations to produce birds which are quite popular in the pet industry, such as with Blue and Turquoise.

Blue Ino = Albino
Green Ino = Lutino
Turquoise Ino or Aqua Ino = Creamino


Inos can also combine with Pallids to produce PallidInos.

Let me know if you want me to elaborate further.

your so awesome.

I think elaborating farther would be great..



Where CAN the INO gene come in handy, like the lacewing, and the pallidino.

What about mixing it in with greys and silvers?

[Jay]

Ino can mix well with Lacewing (Pallid) to produce Pallidinos. Since Ino and Pallid belong to the same family, you can breed Inos and Pallids together and NOT produce split Pallid and split Ino birds. This phenomenon is also called heteroallelism wherein alleles of the same locus (Ino locus for this discussion) have a complementary effect on the final phenotype (appearance) of offsprings. So what this means is that a Pallidino will have a coloration midway between Ino and Pallid.

So in simpler terms, a Blue Pallidino will be a lighter version of a Blue Pallid. A Green Pallidino will also be a more washed out version of a Green Pallid.

Ino will definitely mask Grey since Grey is dependent on melanin to express its color.

Silver (AKA Grey Cinnamon) will not be totally masked because the Cinnamon mutation produces Brown melanin. And as I have mentioned earlier, the Ino gene cannot totally mask Brown melanin.

Ok, i have lutino ringnecks split to blue. I was told this produces albinos, is this correct? If so, what do i need to breed to produce blues? I thought two splits would produce blues since blue is recessive. Help?

[Jay]

Hi there.

Lutino/Blue male x Lutino/Blue hen produces:
25% Lutino cocks and hens
50% Lutino/Blue cocks and hens
25% Blue Lutino (Albino) cocks and hens

"/" sign means "split to"


So you are right. That pairing produces Albinos at 25%. You can't produce visual Blue IRNs from this pairing because both parents carry the Lutino (aka Ino) gene, so all offsprings will be a visual Lutino or Albino. Albinism will mask the Blue color.

To produce a visual Blue offspring, replace one of the parent birds with a parent NOT containing Lutino but should contain the Blue gene either visual for it or split for it.

For example, pair a Lutino/Blue parent with any one of the following will produce you visual Blue babies:

Blue
Turquoise Blue
Green/Blue
Grey
Turquoise Grey

thanks very much.

sorry, my internet was gone for a month. Next genetics;

turquoise.

Now, I know that theres two 'factors' with turquoise... they make turquoise and turq. blue.
and that its hard to differentiate between the two unless you test breed. I just learned that. (see, I CAN learn!)

now, to turq. questions.

I know you can get a LOT of neat pastel-like colors using turq as a base; can I get some easy-to-breed examples of crosses with a turq. male at the start of them?

and maybe some not-so easy ones to boot. like the rainbow *sighs*

and, are there wf/wt turq. yet, CAN there be for that matter? pieds?

[Jay]

I think the Turquoise mutation is the only mutation that blends well with all other mutations... including Pieds and Cleartails.

Turquoise + Lutino = Creamino
Turquoise + Pallid = Turquoise Pallid aka Rainbow

So even with a basic cross, you can already breed magnificent colors. Combining with Cleartail, the color produced is actually a Creamhead-Whitetail, not a WF-WT. The Turquoise mutation allows some yellow pigment (psittacofulvin or psittacin) hence the head is cream-colored and not white-colored unlike other Blue series Cleartails.

for some reason I was imagining a wh/wt on it, like the blues do. I think I like the blues wh/wt better... but that ones is quite stunning in and of itself! thanks again!
