title: The inheritance of constitutive and facultative skin colour.
abstract: Observations on skin reflectance were made on 309 endogamous Indian families, for constitutive (medial upper arm) and facultative skin colour (forehead) to investigate which of the two colours is under a rigid control of genetic action. An assessment of data by coefficient of correlation "r" show that facultative colour is inherited more strictly than the constitutive colour.
