This is interesting it’s the case of a flock of white sheep that have produced only black lambs. The flock of 37 white sheep and 1 white ram have produced a total of 60 black lambs. In sheep the black gene is recessive so in cases where a white ram and a white ewe have both the black and white genes for fleece colour, they have only a 25% chance of producing a black lamb. However, the odds are actually much lower than this as it it a rare occurrence for white sheep to have both the black and white gene. It is thought that the lambs are either the result of a genetic throwback or perhaps a rogue black ram in the area breaking into the field.
