Sequence organization of subtelomeric assemblies. The terminal fragment of each chromosome arm that contains a subtelomeric sequence assembly is depicted. (Yellow) Single-copy DNA; (green) segmentally duplicated DNA unique to a single subtelomere region; (blue) segmentally duplicated subtelomeric repeat DNA; (magenta) unsequenced subtelomeric DNA. Each black arrow within the rectangles depicts a single (TTAGGG)n-like sequence, with the arrow pointing in the 5′ to 3′ direction for the G-rich strand. The position of satellite sequences detected by RepeatMasker software is indicated above each telomere diagram. The positions of the shortest reference alleles for the 8p, 9q, 11p, and 16p telomeres are indicated by a black line segment terminating with an arrow beneath the sequence assemblies for these telomeres.
