DNA is found in nearly all living cells ... he or she can arrange these images to make a composite picture called a karyotype (Figure 10).

Today, most karyotypes are stained with Giemsa dye ... In general, heterochromatic regions, which tend to be AT-rich DNA and relatively gene-poor, stain more darkly in G-banding.

Centromere DNA is typically highly repetitive ... The chromosomal races on Madeira Island and elsewhere show how drive can lead to rapid karyotype change and reproductive barriers between populations ...

Expert Rev Mol Diagn. 2013;13(6):601-611. In other situations, normal microarray analysis in the presence of an abnormal karyotype, such as marker chromosomes, is reassuring, as it indicates that ...
