The multiple regression analyses were undertaken to elucidate the significance and relative importance of different potential determinants of several child development traits (i.e. age at which child 1. turns himself over; 2. sits up; 3. stands up; 4. walks, and 5. cuts his first tooth). Despite the fact that we used a relatively wide gamut of potential determinants (such as parental age, geographic origin, occupation, current residence, or family size) of trait variability, the results of multiple regression analysis (N = 300 families) indicate an almost complete absence of significant factors and studied variables of development. Sibling resemblance component of variance and covariance for five mentioned traits of development and some morphological characters (weight, length and head circumference at day of birth and at 16 months) were studied in 66 families. The transmissibility ("heritability") values for the development traits were small, ranging from 0 ("Turn") to 0.42 ("Walked"). The Findings suggest that there are significant inverse relationship between some of the developmental traits and inborn morphological characters.
进行了多元回归分析，以阐明几个儿童发育特征（即：1. 儿童翻身的年龄；2. 坐立的年龄；3. 站立的年龄；4. 行走的年龄；5. 长出第一颗牙的年龄）的不同潜在决定因素的重要性及相对重要程度。尽管我们使用了一系列较为广泛的性状变异性潜在决定因素（如父母年龄、地理来源、职业、当前居住地或家庭规模），但多元回归分析结果（N = 300个家庭）表明，几乎不存在显著因素以及所研究的发育变量。在66个家庭中研究了上述五个发育性状以及一些形态特征（出生时及16个月时的体重、身长和头围）的方差和协方差中的同胞相似性成分。发育性状的遗传率值较小，范围从0（“翻身”）到0.42（“行走”）。研究结果表明，某些发育性状与先天性形态特征之间存在显著的负相关关系。
