Systematic review on heritability of craniofacial characteristics between the generations of the family

Abstract

Face recognition is one of the most required problems in applied Biometrics. It has been likely to improve feasible techniques for physical world applications after ages of study in this particular area. This study describing findings from various research papers of the genetic of the human face and the aim of this review were to describe the heritability of the facial dimensions and facial features between the generations of the family to better understand the genetic architecture of facial dimensions and facial features also. The study result revealed that the maximum correlation was found between father-son and mother-daughter, while the smallest relationship was observed for numerous of the factors in other-sex couples. The girl demonstrated the same heritage from both parents. Overall face size, lip prominence, and chin demonstrated the strongest heritability, but nose and lip shape indicated the least relationship. The outcome of this analysis shows that there is a relatively effective genetic control in the transfer of facial soft tissue traits. In common, consistent data illustrating soft-tissue facial summaries can be attained from pictures of subjects in correct head poses. Additionally large sample size studies should perform using the parameters from this study that showed the highest correlation.
