2:2 and 3:1 meiotic disjunctions in a carrier of a reciprocal 10/14 translocation.
The offspring of a female with a reciprocal whole-arm translocation between a chromosome No. 10 and a chromosome No. 14 is described. She gave birth to three cytogenetically different children: one with a normal, one with an abnormal but balanced, and one with an unbalanced karyotype. In these three cases, 2:2 disjunctions must have occurred during maternal meiosis. She also had a trisomy 14 abortion, which is assumed to have been caused by a 3:1 meiotic disjunction.
