Relative Applicability of the Classical and the Balance Hypotheses to Man. Especially with Respect to Quantitative Characters

Abstract

Contrasting properties of the classical and the balance hypotheses as applied to quantitative characters were examined in the light of existing data in human genetics. It was concluded that among the loci concerned with a quantitative character in man, overdominant loci are in minority as compared with loci in which genetic variability is maintained by mutation and selection, though the former loci may contribute a large fraction to total genetic variability in the quantitative character.
