A ring Y chromosome was found in a male showing growth retardation and aspermia but normally developed external genitalia. The ring does not display either the characteristic brilliant Y fluorescence or the typical late-replicating heterochromatin.
在一名生长发育迟缓且无精子症但外生殖器发育正常的男性中发现了一条环状Y染色体。该环状染色体既不显示典型的明亮Y荧光，也不显示典型的晚复制异染色质。
