Lutino genetic make-up and best pairings

[finefeatherz]

Hey people ,
Im just getting into the IRN'S and was asking Mike some questions via personal message and thought it would be something of interest to the rest of the forum.

hey mike!

Thanks for your post it really helps me out.

Now can you just give me some info on the genetics with the lutino hen i have and what is the best match for her?? and in breeding where exactly does she stand in the makeup of the different mutations

Also how would it be possible to get a violet or cobalt blue from her?? (or any match up)

If you could PM me back it would be really appreciated thank-you for your time

Krystle originally asked what she would get from the following pairings of ringnecks.

Blue/cinnamon cock with a cinnamon/blue hen

pastel cinnamon lacewing cock with pastel cinnamon lacewing hen

pastel blue cock with a blue/cinnamon hen (the hen is actually a sky blue - cinnamon blue - hen)

Green/blue cock with a Grey hen

Grey cock (dont know if split) with a lutino hen


Answers to the breeding results of these pairs were given by Pinkdevil and myself.

Subsequently Krystle asked what would be best to do with the lutino hen and how she could get cobalts from her birds, especially the lutino.

The lutino is a bit of a loner genetically. Lutino is a sex-linked gene which means that it is a mutation directly linked to the sex chromosomes of the bird. A hen, if she carries the lutino gene, must show the lutino colour. Having said that it can be combined with another colour gene visually to actually appear as a different colour. Thus a white ringneck is a lutino and a blue mutation visible in the same bird. A lutino hen, because of the way her sex chromosomes are passed to her babies, cannot pass her colour visually onto any of her babies. Her sons will however be split to lutino but her daughter won't.

For instance a green cock with a lutino hen will only produce green babies, the males green split to lutino and the hens pure green. For any yellow babies to result the cock has to also carry the lutino gene, so that a green split lutino cock with a lutino hen can produce 505 green babies and 50% lutino babies, of both sexes.

All this means that since none of the birds are known to have any lutino genes except the lutino hen, then no lutino babies will result, however all sons of her will be split lutino. If by chance your grey male is split to lutino then you will get some lutino babies, but until you breed them you won't know.

With the birds you have you cannot get any cobalts or violets. That is a separate gene which none of your birds are carrying - as far as is known. To get into these colours you would have to buy one or more bird carrying these genes. I'm not too sure about the genetics, I would have to read up on it a bit. I suggest you stick with what you have, there are some nice colours potentially in the mix, and by selling the results of a successful breeding season you may raise enough money for the more expensive cobalts etc.

cheers,

Mike
