Well, all siblings will either be split for Blue or Turquoise as the father, being a visual turquoise grey carried both.

Any hens produced will have just one of those two splits, and be either cinnamon or normal.

The males will be visually normal, but split to either blue or turquoise. They will all be split pallid (lacewing) and 50% chance of them being split cinnamon.

Putting a normal blue to a green cinnamon hen will produce these:

If she is split turquoise:

Cocks----
Green split blue and cinnamon
Turquoise split cinnamon
Hens------
Green split blue
Turquoise

If she is split blue:

Cocks----
Green split blue split cinnamon
Blue split cinnamon
Hens------
Green split blue
Blue

thank you for the reply. You really know the genetics.

I am confused as to what happens to the grey gene in the original pair.
Is it possible to be split to grey or does the grey show up as in the greygreen,

Also does anyone have any idea how these would be represented in the punnett square so i can work it out.

thanks again for all your help i am new to this site and am learning a lot

Grey and Violet are actually structural colours, they are either grey or not, or violet, or not, no splits etc. One GreyGreen to a Green will produce 50% GreyGreen and 50% Green, likewise with VioletGreen and Green pairs.

This is also what happens with birds that are Visually Grey (not the greygreen). A visually grey bird actually carries both the blue and grey genes. Your Turquoise Grey bird, is actually three colours in one package. Grey and TurquoiseBlue (turquoiseblue is different to turquoise, as turquoise is a DF variation, rarer and harder to get and impossible to tell appart from normal Turquoise without breeding).

Blue is Recessive, like TurquoiseBlue and the DF turq variant.
Cinnamon is sex-linked Recessive.

Your best bet regarding easy access to fast knowledge of genetics is to muck around with gencalc genetics calculator. Its fabulous, once you have been breeding for a while you memorise it all fast enough though.

A few key notes:

Visually Grey = both visual blue and (sf) grey radio buttons.
Green = nothing checked.
Normal turquoise birds are Visual Turquoise split blue options.

The x1 and x2 stuff is more heavily into genetics and really isnt THAT important to know when getting first into genetics with ringnecks on a usable level. More important for percentages of offspring in mixed mutation pairings etc.

For example, your Turquoise Grey bird, is Visual Grey, Visual Turquoise and split blue and your hen is just the Cinnamon option.

1.0 = male, 0.1 = female.
