KaryoDraw

Karyotypes, explained

Every common ISCN 2024 karyotype, drawn and explained: trisomies, monosomies, deletions, translocations, inversions, isochromosomes, ring chromosomes, mosaicism, and more. Every example is drawn by KaryoDraw and decoded symbol by symbol. New to the notation? Start with the guide on how to read a karyotype, or type any karyotype into the interactive visualizer.
