Figure 8-8. Diagrammatic Representation of Reciprocal Translocation 

 at Points 1 and 2 Between Heterochromatic Segments (shaded) of Two 

 Chromosomes. A and B. with Subterminal Kinetochores. Most of the long 

 arm of chromosome A (LA) exchanges with a part of the short arm of 

 chromosome B (SB) to give a chromosome with a submedian kinetochore, 

 and a small chromosome consisting of a kinetochore plus a short hetero- 

 chromatic segment on either side (SA and LA + SB).
