to be domesticated. Domestication of the Capra aegagrus hircus goats was made easier due to the cross they had with the wild goat breed West Caucasian tur, giving them the important MUC6 gene. This gene is found in the lining of goats and helps protect them from parasites, which are very likely when they are in crowded areas for an extended period of time. The discovery of this gene gave more proof to researchers that the important genes for domesticated animals aren't always related to their appearance. The MUC6 gene makes maintaining goats easier for those who choose to raise them.
