Is The Ability To Wink Genetic?

4.0 based on 41 ratings

Introduction

Winking is a form of facial expression in which one eye is closed and the other is left open for a short amount of time. Not everyone can wink and more often than not, a person can only wink one eye comfortably.

Research Questions

  • Is the ability of a person to wink related to genetics?

Terms to Know

  • The eye
  • Winking
  • Facial expression

Materials

  • Test subject families, the more the better (the families should be biologically related)
  • Pen and paper for notes

Experimental Procedure

  1. Have your test subject family all try to wink.
  2. Record which member of the family can wink and which can not.
  3. Have each member try winking both eyes and ask them which eye is easier to wink even if they can wink both.
  4. Record the information.
  5. Repeat steps 1-4 for all your test subject families.
  6. Evaluate whether you see any trends presented in the abilities to wink of each family.
