Additional File 1. Caryoscope representation of microarray data of 11 S. cerevisiae x S.kudriavzevii hybrids. Array CGH data are shown in numerical order with chromosome I at the top and chromosome XVI at the bottom for each strain. Regions with higher red signal correspond to S. cerevisiae genome regions that are overrepresented in the hybrid genome and those with higher green signal to those regions that are underrepresented. aCGH of wine and brewery hybrids are depicted on black and gray backgrounds, respectively. Arrows indicate potential non-reciprocal recombination events between homeologous chromosomes involved in the generation of chimerical chromosomes.
