Re: a brother/sister mating - what problems would it cause?
didnt want to read and run, but would have thought it was a very bad idea, any genetic faults would be multiplied, even brother and sister matings are far too close for line breeding.

Re: a brother/sister mating - what problems would it cause?
I woulden't like the idea of dog bred closer than grandparents
especially unhealthested ones. I know someone suggested letting Rusty mate with Maya, I told them where to go ![]()

Re: a brother/sister mating - what problems would it cause?
TBH probably very little problems in the F1 gen.... but if each sibling was to keep multiplying the problems with the breed as a whole would likely multiply!
I must apologise for any post tonight. I've been on the vino and its likely I wil regret it in the morning! ![]()

Re: a brother/sister mating - what problems would it cause?
With the number of hereditary problems GSDs have and Huskys can have problems with eyes and because of bad breeding now as their popular there seems to be other things occuring. Any thing each are carrying whether it be affected or just a carrier is likely to come out as there is no genetic escape.
As its a double recessive genes. |

Re: a brother/sister mating - what problems would it cause?
thanks for the info, was quite shocked they said yes, they took the pics of the parents off and i cant find the advert now! was quite obvious that they were brother/sister really!
lets hope they dont sell 2 together! i dont understand why i keep seeing so many gsd cross huskys for sale. doesnt sound like a great cross, some are nice looking though.

Re: a brother/sister mating - what problems would it cause?
To make wolf like dogs maybe I've seen quite a few doing canix. I wouldn't do you can increase the risk of genetic problems being passed down. Course I'm sure some breeders will tell you it's perfectly ok

Re: a brother/sister mating - what problems would it cause?
Quote:
The F1 generation will have problems. You are breeding together two animals that are closely related ie brother and sister. They could therefore both be carriers of a deleterious recessive gene, and so will produce affected offspring "aa". The siblings are the Aa pairing in the above diagram. If the gene is dominant then homozygous dominant individuals may be produced with very severe disease or it may be a lethal combination. Of course there are also immunity problems and all the other inbreeding issues too.
