I can bore people to death with sheep genetics
but in ouessants the important things to look for are two white parents producing a black offspring this means that the black lamb is a true recessive back and cannot carry dominant black.( this canb e useful for breeding programmes)
A white lamb born to two black parents this is very significant because for the lamb to have been born white one of the parents must have been carrying dominant black and hiding the fact they are in reality a white sheep.
why is dominant black so important; well it is and it isn't; many breeds of sheep are thought to have dominant black black welsh mountain and jacobs even though they are white ( long story) the important thing with dominant black is it hides other colours ( but not brown) so if there are other patterns of sheep out there that may be in ouessants you may have them but not know because your sheep are dominant black its a moot point if it is in ouessants at all but the more recording of colours and breeding the more likely people are to find the answers;
