Abstract

Background: Asymmetry of bilateral measurements in human body is a common phenomenon and low asymmetry predicts canalization and developmental stability of morphological characteristics.

Methods: A study was done in 2012 on fluctuating asymmetry (FA) of hands and feet (length and breadth) among 135 girl students, aged 18–22 years in a University in Bilaspur, Chhattisgarh, India.

Results: Mean individual absolute FA was 0.01 for each bilateral trait. Paired difference between two sides of hand and foot dimensions was not significant except for hand breadth (t= 2.03, p< 0.05). Correlation between bilateral measurements of hands and feet (length and breadth) was significant (p< 0.05) and asymmetry was marginal. In conclusion, low bilateral asymmetry and high correlation between sides indicate canalization, similarities in environmental as well as developmental-genetic programs for these dimensions of hands and feet.

  1. How interesting would it be to explore the fluctuating facial asymmetry in populations living under extreme stresses of the environment? That would reflect on the ability of the populations for self-regulation and canalization during growing period.
