In our assessment, a series of distinctions exist within the developmental cascade among both monozygotic and dizygotic twins and their co-twins. Previous studies have allowed us to highlight certain differentiating phenotypic traits; however, the present investigation focuses specifically on differences in artistic expression, namely drawing and calligraphy, among twins. Our findings confirm the existence of such differences, which may hold significant implications for the comprehensive study of twin genetics and epigenetics. Furthermore, we documented that a form of intra-pair competitiveness occurs in some twin pairs, with this behavioral tendency being more prominently expressed by the second-born twin in relation to the first-born twin, rather than the converse.
