6、ment used.,C-banding stains centromeres. R-banding is the reverse of C-banding and stains non- centromeric regions. G-banding is obtained with Giemsa stain. It yields a series of lightly and darkly stained bands. Q-banding is a fluorescent pattern obtained using quinacrine for staining. The pattern
