Extended Data Fig. 6. Positions of ampliconic gene families on the Y chromosome.

Locations of protein-coding ampliconic genes, grouped by family, are shown with sequence class annotations and palindrome locations on each Y chromosome. The tracks for each species are: (1) sequence class annotation, (2) palindromes, and (3-9) ampliconic gene families: BPY2, CDY, DAZ, HSFY, PRY, RBMY, TSPY, and VCY. The sequence class track has a discrete class annotation for every base. All other tracks are displayed as presence/absence (color/no color) with the ampliconic gene family tracks containing a horizontal midline to help the eye with the sparse display. All Y chromosomes are plotted on the same scale.
