Reciprocal translocations in man. 3:1 Meiotic disjunction resulting in 47- or 45-chromosome offspring

J Med Genet. 1975 Mar;12(1):29-43. doi: 10.1136/jmg.12.1.29.

Abstract

Five cases of chromosome imbalance resulting from 3:1 disjunction of reciprocal translocations are described. A review of the literature suggests this phenomenon is more common than has previously been recognized.
