Three Genes Determine Dogs’ Coat Type

Labrador dogUniversity of Utah researchers recently published findings from a study that demonstrates only three genes, RSPO2, FGF5 and KRT71, control the seven types of coats found in purebred dogs.  Variations in the genes control length, curl and texture.  Of the three genes, RSPO2 is associated with dogs’ moustaches and large eyebrows.  FGF5 is linked to fur length.  KRT71 determines if the fur is curly.  Texture is attached to both RSP02 and KRT71.  While this information is interesting on its own, it also can help scientists understand complex human diseases that are caused by multiple genes.  For more information, see Science Daily.
