| stephen700 said: Certainly wikipedia is a reliable enough reference for me - it sais , "inbreeding results in more recessive deleterious traits manifesting themselves". If general fitness were the target a pure breed with no recessive bad traits will be more than equal to a mongrel which has multiple recessive disorders (ie outbreeding)- nature continually eliminates recessive disorders in populations via inbreeding or and outbreeding. In a healthy population closely related animals including humans will produce very successfull offspring. There are also recessive advantages which are expressed by population imbreeding these beneficial recessive traits are also a very important driving force of population genetic changes - Evolution is more complex than most people realise and there are no rules.

inbreeding is actually very common in horse breeding business
1/2 siblings, 3/4 siblings....that will make their bloodline even better.
