The study investigated the relationship between color blindness and sex-influenced genes by examining the index-to-ring finger length ratio and conducting an online Ishihara test for color blindness. All participants were found to have normal color vision, and variations in finger length ratios were observed, with some participants having longer index fingers, longer ring fingers, or equal lengths. The research aimed to explore the potential genetic link between these traits, although no color blindness was detected in the group.
