Hand clasping and arm folding in the Basque population.

Area of Science:

• Anthropometry
• Human Genetics
• Behavioral Science

Background:

• Hand clasping and arm folding are non-random, genetically influenced behaviors.
• Previous studies suggest population-specific variations in these traits.

Purpose of the Study:

• To investigate the prevalence of hand clasping and arm folding in a Basque population.
• To examine the association between these two behavioral traits.
• To compare Basque data with other Spanish populations.

Main Methods:

• A sample of 286 males and 455 females from the Basque population was assessed.
• Participants were observed for their preferred hand clasping (right or left type) and arm folding (right or left type) methods.
• Statistical analysis was performed to determine correlations and compare with existing data.

Main Results:

• A significant correlation was observed between hand clasping and arm folding preferences.
• Specifically, a strong association was found between the right type of hand clasping and the left type of arm folding.
• Results were compared with data from other Spanish populations, highlighting potential regional differences.

Conclusions:

• The findings confirm a strong genetic linkage between hand clasping and arm folding behaviors in the Basque population.
• The observed correlation provides further evidence for the heritability of these traits.
• Comparative analysis suggests potential genetic differentiation among Spanish populations regarding these anthropometric markers.
