The Wyandotte Thread

Katy you have some SQ SLW......trust me, it doesnt matter if you show them or not, if you did show them you would be having alot of fun.

Thanks! We know they've certainly got SQ in their ancestory don't we.

Yes, all animals have the potential to carry recessive genes that control undesirable traits. When breeding "close", more homologous pairs of genes are formed. Many deleterious traits are recessive, but so are many desirable traits. So, when the genes are doubled-up, we see the traits. We can select for them or against them. This means that by using inbreeding along with the right selection technique, you can select against the undesired traits and even eliminated them from the line. At the same time we are more likely to "fix" desirable traits.

With humans, we don't practice selective breeding, so we shouldn't procreate with relatives. With animals, we can test cross, out-cross, inbreed and line breed at will - and all with the same animals as one of the parents. The immune system will eventually become compromised with extended inbreeding, but no other undesired trait will remain in the line if you actively breed against it with the proper crosses. All breeds of domestic animals including strictly ornamental types, were created with a certain amount of inbreeding. Indiscriminate inbreeding is never a good thing, but purposeful inbreeding in the hands of the knowledgeable person can do amazing things.

Thanks again Steve

I moved this conversation here - I hope you (and BCBrian) don't mind me asking so many questions, but I find it interesting and something I never gave much mind to before. Having chickens is inspiring me to learn more and maybe one day, contribute to revitalizing one of the at risk breeds.
 
That was a great post by McSpin,

The most inbred animal on earth is the white lab mouse (Jaxxon strain) - they are so inbred that for all intents and purposes they are all identical twins now - so much so, that they can even swap organs without rejection. They are now more than 100 generations of straight brother-sister matings - the highest inbreeding coefficient one can do.

Without rigorous selection, most inbred animals begin to accumulate so many sub-lethal genes, that after a dozen or so generations - they become extinct.

BUT- with the application of very rigorous standards of selection, the modern laboratory white-mouse strain has proven to be longer lived, healthier, and more fertile than their wild-brethren.

Inbreeding - in itself - is not what's harmful - it's inbreeding without rigorous culling for faults that causes all of the problems.

In fact, it is with in-breeding that every man-made colour, and man-made breed of livestock was created.

Rather than being afraid of it - people should learn how to use inbreeding. Inbreeding and line-breeding is just a tool - whether the tool is used to build or to destroy - is up to the wisdom of the person using it.

Here are some images of my 18 month old Splash hens from Strombergs Hatchery. When I posted pics of the day old chicks some folks commented that the chicks were very light colored and wondered if continuous breeding of Splash to Splash has diluted the color.
