Size and shape components of Mahalanobis D2 were computed from a set of anthropometric characters among the Yanadis, a tribe in the south eastern part of Andhra Pradesh, India. These people are in a transitional stage of development and show differences in sociocultural variables between different geographical regions. From the study it appears that the pattern of differences due to size and shape is the same as that of general distance, irrespective of whether the distances were computed for male, female or pooled data, with some exceptions for females. The noteworthy finding is that the shape components for men and women dominate and are more similar than corresponding size components, thereby indicating that males and females are morphologically similar with respect to their relative measurements. The association of the morphological distances for the five breeding populations with the corresponding road, map and migrational distances were also investigated using simple and partial correlations. The results suggest that the migrational distance among the three is the strongest influencing factor for the morphological differences. The road distance also maintains a very high degree of association, especially with shape components.
马氏D2的大小和形状成分是根据印度安得拉邦东南部一个部落亚纳迪人的一组人体测量特征计算得出的。这些人正处于发展的过渡阶段，不同地理区域的社会文化变量存在差异。从研究中可以看出，无论距离是针对男性、女性还是合并数据计算的，大小和形状导致的差异模式与一般距离的模式相同，女性有一些例外情况。值得注意的发现是，男性和女性的形状成分占主导地位，且比相应的大小成分更相似，从而表明男性和女性在相对测量方面形态相似。还使用简单和偏相关分析了五个繁殖种群的形态距离与相应道路、地图和迁徙距离之间的关联。结果表明，三者之间的迁徙距离是形态差异的最强影响因素。道路距离也保持着非常高的关联度，尤其是与形状成分。
