Abstract

The data presented here indicate that different influences affect dermatoglyphic pattern development in MC-MZ and DC-MZ twins. Only five of 84 variables had significant mean differences but their clustering suggested a real difference in mean placement of the atd angle. Nineteen of 84 variables had significantly different within-pair mean squares for the two twin types. Larger numbers of twins will be required to obtain accurate estimates of the magnitude of the dermatoglyphic differences between MC-MZ and DC-MZ twins. Studies of dermatoglyphics in MC-MZ and DC-MZ twins are important to the understanding of factors which influence early embryonic development and when better documented may provide a mechanism for retrospectively diagnosing placental type of MZ twins.

摘要

此处呈现的数据表明,不同影响因素作用于单绒毛膜单卵双胞胎(MC-MZ)和双绒毛膜单卵双胞胎(DC-MZ)的皮纹模式发育。84个变量中仅有5个具有显著的均值差异,但它们的聚类显示出a - t - d角平均位置存在真正差异。84个变量中有19个在两种双胞胎类型的配对内均方上存在显著差异。需要更多数量的双胞胎才能准确估计MC-MZ和DC-MZ双胞胎之间皮纹差异的程度。对MC-MZ和DC-MZ双胞胎进行皮纹学研究,对于理解影响早期胚胎发育的因素非常重要,并且如果有更完善的记录,可能为回顾性诊断MZ双胞胎的胎盘类型提供一种机制。
