染色体核型分析结果为46,XY 46,XX,无其他

染色体核型分析结果为46,XY 46,XX 但是在分析结果图中染色体有些阴影较重,不是打印效果不好,是同一张报告中能明显看出部分染色体阴影重,这是怎么回事啊?忘高手给予解答,小弟不胜感激!!!
谢谢回答的这两位,我没有说清楚,这是我和我媳妇的,我的报告中染色体颜色均匀,但是我媳妇的报告中染色题有一些看上去阴影较重,我想知道这是怎么一回事

如果制片没有问题的话,你没有分析错的话,这个是嵌合体,常见的嵌合体有46,XX/46,XY,45,X/46,XY,表现出两个或者更多,来自不同胚胎的细胞株。考虑是真两性畸形,体内同时存在有卵巢和睾丸组织。真两性畸形2/3的病例是46,XX核型,1/10是46,XY核型,其余是嵌合体。
你事G显带吗?如果阴影中重,原因有很多种,可能是渗透时间长,染色体过度膨胀,滴片没有做好,也可能是染色不均匀等等
