Figure S3 Changes in ploidy within experimentally selected populations. Cell populations were stained with SYTOX Green and sorted by flow cytometry as described. (A) S. cerevisiae haploid and S. cerevisiae/S. uvarum diploid. (B) Vessel A: 101gen (2 N), 157gen (mixed 2 N + 1 N), 224gen (1 N); (C) Vessel B: 115gen (2 N), 125gen (mixed 2 N + 1 N), 135gen (1 N); and (D) Vessel C: 43gen (2 N), 51gen (mixed 2 N + 1 N), 95gen (1 N).
