title: A family study of lactose tolerance.
abstract: Survey data from 38 families consisting of both parents and at least one biological offspring provided no support for the belief that lactose tolerance resulted from having at least one dominant gene on an autosomal gene pair and did not support the belief that Caucasians are more frequently tolerant of lactose than are persons of Oriental or of mixed Caucasian-Oriental ancestry.
