But Border what role does genetics play in ear development? Collies are known for their naturally shaped ears, which are often semi-erect or fully pricked. Superficial breed standards call for this type of ears, but there are some differences between mixed dogs and purebred dogs, and genetics are thought to play a major role.
Border Collie Ear Genetics and Shape: Like human ears and other characteristics, Border Collie ear shape and condition (upright or floppy) is largely determined by genetics. It is believed that pricked ears are a dominant gene compared to recessive genes for floppy ears. However, this is unlikely to be a simple Mendelian trait and is likely to be polygenetic involving multiple linked genes, for example those controlling ear cartilage. This may explain the variation in collie ears with their condition from erect to floppy and shape from tulips, planes, buttons to long bunny ears.
