Subfamilies on the AluYh lineage.

Putative subfamily	Species	Mutations from AluYh3 consensus	Copy number	Polymorphic?
Yh9	H	97G, 161G, 167G, 230T, 234G, 249T	2	Y
Yh7	H	97G, 161G, 167G, 234G	20	Y
Yh3a1	H, C, G, O	99A	98 (H), 73 (C)	-
Yh3a3	H, C	99A, 237C, (238–259 del.)	3 (H), 11 (C)	UN

Copy number of the AluYh7 subfamily includes elements with the diagnostic mutations for AluYh9. H = human, C = chimp, G = gorilla, O = orangutan, UN = unknown, Y = yes. Copy number in the gorilla and orangutan genomes is unknown due to the absence of complete genome sequences for these species.
