I'm not convinced that that this deformity was all down to father X daughter cross either.I am still not convinced that the abnormality was due simply to a father x daughter breeding,
All that I can say without any doubt is that recessive conditions are much more likely to occur when the mating partners are related. Breeding to an unrelated animal is less likely to give these problems if 'new blood' can be introduced. Giving 'bed and board' to a neighbour's rams/bucks or other males is ideal if the facility exists.
Look no further than the British royal family or the pharaoh lines to see the effect of breeding too close in humans. Haemophilia came to Victoria's offspring this way. (I'm not anti the Royals)
Back to the lamb.....it was probably just some unfortunate example of 'these things happen', but consanguinity may have played its part.
