EAST TEXAS HOG DOGGERS FORUM

Just out of curiosity...

I have a buckskin BMC gyp.  This gyp was out of one of my hunting partner's litters that he raised.  Of this litter, about half the dogs were buckskin and half were saddleback. (in other words she has saddleback littermates)

If I breed this buckskin gyp to a solid buckskin male (who is from a line of all solid bucksin dogs), is it possible that she will throw saddleback dogs?

I've done some reading as to coat colors and which are dominant and recessive, but it seems to vary by breed.

I don't have a doctorate in genetics by any means but I do have a pretty good grasp and off the top of my head, I believe that the saddle back coloration is a single gene mutation as opposed to a double modifying allele. (saddle back is not the coloration that I I have studied)

It would help to know a little more background on the gyps lines and historic color traits but based simply on the information provided, it seems mathematically reasonable to expect a 10 to 15% chance of throwing at least one saddle back.

Of course genetics being the tricky thing that it is, mathematical probability can not tell you if that 10 to 15% chance will effect only one pup or all of them. Or none assuming that you don't hit that 10% lotto.

Id consider myself lucky if I got more than one saddle back from the breeding described, assuming thats what you want.

i would think there is a good chance of getting some saddle back pup.

Thanks Monteria!

I'm just planning to breed some exceptional dogs...a nice paint job would just ice the deal!

BTW, If this is an outcross in a tight line program, and you intend to go back to the gyps line with a pup, your chances of throwing saddlebacks increase exponentially with each generation of your new line breeding program.

Does that make sense?

If you breed one of the progeny back to its mother, your chances of throwing a saddleback increase. That opportunity will multiply with each generation of line breeding as each generation will have more and more of the mothers genes with each generation.

Im pretty sure that you knew that already, right?.?.....

I hadn't even thought of that, but yes...my male I intend to breed will actually be a hybrid vigor outcross to the linebred gyp.  I also own the sister to this gyp I intend to breed and she is a saddleback.  Although she's pretty good, she isn't quite the dog and lacks a little of the confidence that her sister has.

My hunting partner has been breeding these curs for quite sometime.  Unfortunately, all the older dogs have been killed or have died and all he has left is basically a yard full of brothers and sisters.  He had an accidental breeding a while back of two littermates.  While these are inbred (as opposed to linebred) dogs he kept them all, and all are showing extreme promise.  They're about seven months old, and are hunting machines.  He recognizes that inbreeding can produce throwbacks from MANY generations past and doesn't intend to breed any of them.

When you find yourself in the position your buddy has, one generation of inbreeding before an F1 outcross for  reintroduction of a 0% coefficient to that line may be just what the doctor ordered.

Of course that could backfire but you would know immediately and if the whole inbred litter is rocking at 7 months, I guess it didn't....... You would definitely know before they were of breeding age anyway.

Its pretty dang cool to watch a depressed line come to life at the F2 or F3 stage of line breeding (assuming that F1 is the outcross). I kept two out of my recent F2 cross and they are JAMMIN for 7 month old pups.

 :o WHEW, my head hurts just reading this, ya'll is way smarter than me.
I thought and F1, F2, or and F3 was the intensity of a tornado.  ;D:-[

Keep it up good information here.
