In dogs there are certain colors which when bred together are 100% fatal. I would wonder if this is similar.

All:

I am a newbie, but, my understanding is that white is a recessive trait....should it be 'extended' or bred out? I really don't have an opinion, just trying to understand..

OMGosh!! I have never heard that there are colors of dogs that when bred together proves fatal to the puppies!!! What color(s) are they? How bizarre that something as seemingly simple as color could affect life & death.

Just as an example, I have a solid white boxer with blue eyes. As a puppy we had to watch her to make sure she wasn't deaf. And we were strongly advised to not breed her because dogs like her have a very high chance of throwing blind puppies. It all has something to do with the white genetics... I have zero idea if the same principles would apply to white chickens.

wow wlhtx,
That's really something. It's a shame, too, your Boxer sounds gorgeous. You're in east Texas? I'm near Woodville, how about you?

I don't know if the genetics are similar or if it a different issue.

See the section on double-Merle breeding in this article on Australian Shepherd dogs:

And here is lethal white syndrome in horses:

It's because the genes are linked together. The genes for Dalmatians to have round spots instead of splotches is linked to a gene that makes them unable to digest liver. I have a breed of dog that was created recently, it's a wirehaired vizsla. They used regular vizsla and German wirehaired pointers. Now we have see that somehow the breed got a genetic predisposition to idiopathic epilepsy, which doesn't exist in the other breeds. Not sure what it is caused by but must be linked to some trait people wanted the wirehaireds to have.

White is often the most problematic color in most breeds.

I raise Border Collies....we do not breed white factored dogs, white headed dogs to another one similar as there is a high chance of genetic defects. IF you breed white factored or white headed, you bred to a mostly dark dog (with parents that are dark)....or good breeders do...I have done a lot of research since one of my sire was a white factored dog.

Breeding mostly white to mostly white or merle is not a good idea....if the pups have white ears, chances are they will be deaf....

so bottom line, if you bred a whitish dog, breed to mostly dark and you still will get pups white...but do not bred white to white or you will get health issues.....

In a nutshell, do not breed white to white.....but bred white to dark...you still will get white offspring but a far less chance of genetic issues....

if you bred white to white, the first offspring may not show the issues but their offspring may but by then you have invest time/most/livestock and may have to cull the entire lines...so if you are going to bred the White Legbars, breed to a dark hen .....

(White factor= means having white running up the back legs and belly)

sounds similar to that trait in cats, that most (all?) white blue-eyed cats are deaf.

She is geriatric now, but in her hey day she was absolutely gorgeous. She was so white she would sparkle in the sunlight.

We are a little south of Marshall and enjoying a cloudy 75 degree day in late July. It feels like a late September kind of day!
