The genome of three different evolved clones will be sequenced at Genoscope: one clone isolated at 2,000 generations, hence before the emergence of the polymorphism, and one clone from each distinct morph isolated at 40,000 generations, to investigate the molecular mechanisms underlying their evolutionary divergence and coexistence. These genome sequences will be compared to the one of the ancestor clone, already available through a common sequencing effort between the Genoscope and the Korea Research Institute of Bioscience and Biotechnology (KRIBB, Dr. Jihyun F. Kim, Republic of Korea).
