Abstract

The unusual appearance of a ring XY bivalent at metaphase I of meiosis is reported in some cells of an oligospermic human male. Higher than usual frequencies of ring configuration in the XY pair were also observed during prophase I. The defect could be attributable to loss of some DNA sequences from the distal heterochromatic tip of the Y chromosome long arm.

摘要

在一名少精男性的一些细胞中，报告了减数分裂中期I出现XY环状二价体的异常现象。在前期I也观察到XY对中环状构型的频率高于正常水平。这种缺陷可能归因于Y染色体长臂远端异染色质末端一些DNA序列的缺失。
