Other claims from this paper (5)
- Method / resource Salix herbacea has approximately 8 Mb Z and W regions on chromosome 15.
- Observation The W region contains an embedded 5 Mb inversion.
- Association The inversion appears to have recently incorporated pseudoautosomal sequence, nearly tripling the W region.
- Observation PISTILLATA pseudogenes occur in ZW Salix species.
- Observation PISTILLATA pseudogenes were absent from XY Salix species.
