  1. This table shows the extent of conservation of the eight ancestral chromosomes (AK1-8) and 24 genomic blocks (GBs) of the duplicated Ancestral Crucifer Karyotype (ACK) in Pachycladon and Australian Camelineae species [10]. PK- Pachycladon karyotype (n = 10), BA - Ballantinia antipoda (n = 6), SL - Stenopetalum lineare (n = 5), and SN - S. nutans (n = 4).
