Differences between the right and left hand in ridge counts and pattern type counts were analyzed using data obtained from 711 families consisting of all parents and 2,466 children. Heritability estimates for each trait were derived from regressions of offspring on either parent or average value of the two parents, and from full-sib correlations. These estimates varied from 0.09 for bimanual difference in the number of arches to 0.24 in the number of ulnar triradii. The low expected value of heritability for bimanual difference in dermatoglyphic traits was demonstrated.
利用从711个家庭（包括所有父母和2466名子女）获得的数据，分析了左右手在嵴纹计数和花纹类型计数上的差异。每个性状的遗传力估计值来自后代对父母一方或父母双方平均值的回归，以及全同胞相关性。这些估计值从弓形纹数量的双手差异的0.09到尺侧三叉点数量的0.24不等。皮纹性状双手差异的遗传力预期值较低得到了证实。
