✦ Synopsis

A commingling analysis of the distributions of obesity as quantified by Quetelet's index, triceps skinfold, suprailiac skinfold, umbilical skinfold, subscapular skinfold, a trunk-extremity ratio of skinfold measurements and Quetelet-adjusted trunk-extremity ratio was performed in a population of 9,226 individuals living in Tecumseh, Michigan, during 1962Michigan, during -1965. For all but the (non-Quetelet-adjusted) trunk-extremity ratio, two or three distributions were needed to fit the data adequately even after performing a power transformation to eliminate skewness. Although this evidence is compatible with a major gene effect, segregation analyses of these data using the unified, mixed model are necessary to resolve whether the commingling is due to a major gene.
