I took a genetics class in 10th grade. We covered eye color with Big B and little b. We discussed dominant traits and recessive traits. Attached ear lobes or dangling ear lobes. Tongue curler or not a tongue curler. There were others.
I am curious to find out about whether the following is a genetic trait.
Okay reader, imagine yourself on the phone. An imaginary phone call if you will. Hold you hand up to your head like you were on the phone.
Are you a "pinky to the mouth, thumb to the ear" imaginary phone person? Or are you the "closed fist to the cheek" imaginary phone person?
