Abstract

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.

摘要

本文描述了一位女性的后代情况,该女性在10号染色体和14号染色体之间发生了相互的整条臂易位。她生下了三个细胞遗传学上不同的孩子:一个核型正常,一个核型异常但平衡,一个核型不平衡。在这三种情况下,母源减数分裂期间必定发生了2:2分离。她还经历了一次14三体流产,推测是由3:1减数分裂分离导致的。
