Personally I think you need to have the double co-efficient x for inbreeding at least at 25% or more to be really identified as inbreeding. You must remember the sire can only pass on his X chromosomes to his daughters. You often hear Ryan refer to the x path. The easiest way to understand this is to do some simple inbred testmatings. For example Bombastic Shiraz x Miata his daughter. Brett Lee with Bettys Angel should give you above 25% inbreeding but if you mated Lochinvar Marlow with Bettys Angel the inbreeding will actually be similar or higher as BL lies in the X path of Lochinvar Marlow even though further back in the pedigree. Its really quite interesting. Fernando Bale has been a success at stud I think most would agree even though he has had a large number of quality bitches. Its interesting to note though that 18 of his top 20 offspring are males and do not carry the X factor from Fernando. It will be interesting to see how they go at stud. Its a little early to say IMO to see how he will shape the breed as not many of his daughters who carry his X chromosomes have had litters. JMO. Cheers
A litter from a breeding that results in 25% coefficient of inbreeding is the equivalent of a full brother X sister breeding or a Parent X offspring breeding. An Uncle x nice breeding has a 12.5% coefficient of inbreeding. So if as said above Uncle x Niece is considered inbreeding than 12.5% coefficient of inbreeding would have to also be considered as inbreeding. And technically any number other than 0 as the coefficient of inbreeding means that the dog is inbred

18.8% x 2 is in no way to close imo !!!!

Yes I'd class that as inbreeding......no I don't believe its too close. As long as the bitch had good ability.....anything is possible.
I plan to do this in the future.
I can't do the link though.

Hi Rick. Just "Right click" the "address bar" and then "Left click" to get the "Dropdown tag". Select "Copy" & then simply paste it in your reply. It's as easy as that. Go on, be brave & have a go. After using this site for 20 years it's time you learnt mate lol. Cheers ;-)
