Inos - Trying To Understand The Genetics

Featured Replies

Posted

I may be getting an albino to replace Twitter in my breeders, so I've been trying to wade through the genetics.

 

As I read, ino is recessive sex linked, a male needs 2 ino to appear ino.

 

The mother of these babies is a normal blue. The dad is albino. I came up with these squares for the babies.

 

 

 

Hen: ZW Cock: ZiZi

 

 

Zi Zi

 

Z ZZi ZZi

 

 

W ZiW ZiW

 

 

Am I wrong in assuming that any of their offspring the appears ino would have to be female? My head is hurting from crunching throug this! LOL I'm looking forward to hearing back.

okay, I'm getting the hang of it! I don't like the results of the next step though. If I buy an albino hen, ZiW, and breed her with anything but an albino male, or at least a split male, I'd have no chance of getting albino babies. The best I could hope for would be albino split hens, and of course I'd not know, unless I kept them and bred them a few times. Right?

 

I guess I can always hope that one or more of my current boys are split for ino.

Hi all of your males from the pairing you mentioned will be split for ino and all of your hens will be ino so you can sex them all as soon as they hatch.

That is only if you have them breeding separately and not in a colony because you cannot guarantee the father in a colony.

There is always a chance your male is split for ino though and then you can expect ino in both sexes.

You also mentioned albino split hens which are not possible as the hens can't carry the ino gene in split form.

ALL the males from that pair (ino hen non ino male) would be split for the gene. Hens can not be spilt for sex linked genes.

 

if you use a split male with the ino hen then you will get some of both genders.

 

I use INO for the gene nothing to do with colour.

I'm fairly certain these are not colony bred, since she's told me what the mom and dad are. I'll certainly confirm before I bring my new baby home.

 

I can't believe I referred to split for hen. I've wrestled with this at least a dozen times, and I KNOW that doesn't happen... and I know why... I just can't get it out of my head!

 

Some days are just more blonde than others. Thanks for setting me straight.

 

I have committed to getting this little girl. She should be ready in early December. Now to come up with a name, Snowy comes to mind, and figure out how to tell my boyfriend.
