SEX CHROMATIN IN NEWBORNS: PRESUMPTIVE EVIDENCE FOR EXTERNAL FACTORS IN HUMAN NONDISJUNCTON

A ROBINSON et al. Science. .

Abstract

An incidence of 0.6 percent of sex-chromosome aberrations in newborns was found during a 5-month period, while no aberrations occurred in similar populations before and after this period. Down's syndrome also exhibited an elevated frequency during this same critical interval. A severe rubella epidemic may have influenced this pattern.
