A number of cases of intersexuality occurred in a fairly large number of cases in 6-8 months-old laying hens on two poultry farms in the province of Limburg. When macroscopic and microscopic studies failed to supply any evidence concerning the cause of the considerable development of the right gonad, it was decided to do a chromosome analysis. Three intersexes in which the chromosomes were studied, were found to be triploid birds showing a ZZW sex chromosome combination, which aberration may have been the cause of the intersexuality observed.
林堡省的两家家禽养殖场中，相当数量的6至8月龄产蛋母鸡出现了一些雌雄间性的情况。当宏观和微观研究未能提供任何关于右侧性腺显著发育原因的证据时，决定进行染色体分析。对三只进行了染色体研究的雌雄间性个体进行检查后，发现它们是三倍体鸟类，呈现ZZW性染色体组合，这种畸变可能是观察到的雌雄间性现象的原因。
