Genetic studies in some ethnic groups of Pakistan (Southern Punjab): Colour blindness, ear lobe attachment and behavioural traits

Abstract

Frequency distributions of colour blindness, adherent ear lobe, hand clasping, arm folding and leg folding are reported for different ethnic groups (Balochs, Rajputs, Syeds, Pathans, Araeen and Jats) for Pakistan (Southern Punjab). The F-analysis suggests an insignificant difference between these groups, though the LSD value indicates a significant difference of Balochs with the other groups. The association Chi-square values suggest the independence of the three behavioural traits.
