In Lucilia cuprina C-banding produces procentric bands on all autosomes and deep staining over most of the X and Y chromosomes which conciderably facilitates the analysis of complex Y chromosome rearrangements. The Y chromosome is generally darkly C-banded throughout while in the X chromosome a pale staining segment is found in the distal portion of the long arm. Modulation of the banding reaction results in 'grey' areas in both X and Y. When C-banding is compared with allocycly it is clear that not all heteropycnotic regions in the sex chromosomes C-band to the same extent. Secondary constrictions in the short arms of both X and Y chromosomes are clearly revealed by C-banding, the X satellite being polymorphic for size.--Q-banding results in a brightly fluorescing band in the short arm of structurally normal Y chromosomes. This band loses its fluorescence in some translocations, probably through a position effect. Hoechst 33258 staining does not produce any brightly fluorescing bands.
在铜绿蝇中，C 带在所有常染色体上产生着丝粒带，并且在大部分 X 和 Y 染色体上染色很深，这极大地促进了对复杂 Y 染色体重排的分析。Y 染色体通常在整个长度上 C 带染色很深，而在 X 染色体中，在长臂的远端部分发现一个浅染区段。带型反应的调节会在 X 和 Y 染色体上产生“灰色”区域。当将 C 带与异固缩进行比较时，很明显性染色体中并非所有异固缩区域的 C 带染色程度都相同。C 带清楚地显示出 X 和 Y 染色体短臂中的次缢痕，X 随体在大小上具有多态性。——Q 带在结构正常的 Y 染色体短臂中产生一条明亮荧光带。在一些易位中，这条带会失去荧光，可能是由于位置效应。Hoechst 33258 染色不会产生任何明亮荧光带。
