a Positions (triangles) and copy names of RR17 genes and partial duplicates on the S. exigua Y, S. purpurea Z, and S. purpurea W chromosomes. Triangles are pointed in the direction of the sequence relative to the original RR17 gene (XM_024590879.1). Dashed lines show the homology between RR17 partial duplicates on the Y and Z chromosomes. Large arrows on the W chromosome indicate full length intact RR17 copies. b Homology of RR17 partial duplicates relative to the intact RR17 gene in Populus trichocarpa. Red arrows represent partial duplicated of RR17 in S. exigua and are positioned according to their homology with the full length intact RR17 gene (Blue boxes). Purple arrows represent copies in S. purpurea positioned with their homology relative to the intact copy of RR17. * indicates the duplicated palindromes within 10 bp in length.
