MadSci Network: Genetics |
Hi Celeste, Sorry it has taken a while to reply but there have been some network problems. Ear wiggling is not as far as I can find out an exclusively genetically inherited trait as there are only a few known characteristics that are controlled by only one gene. Being able to roll your tongue is one of these. Ear wiggling is quite a complex skill requiring both muscular action and concentration so it is possible that someone may have an inherited predisposition to ear wiggling but will not actually be able to do it unless they practice. Maybe you could do some research on the subject by finding people who can wiggle their ears and asking if anyone else in their family can do it.
