Increased DNA damage in the hybrid. a Increased formation of foci indicative of DNA damage in hybrid. Fraction of cells showing RAD52-GFP foci in the hybrids and its diploid parents grown in SD (N = 4, ~2000 cells). For the hybrid, the results are shown when tagging either the S. cerevisiae or S. paradoxus allele. b The hybrid shows signs of DNA damage stress through protein localization. Chaperones that are known to localize into punctates during DNA damage are observed in the hybrid (Additional file 6: Table S2)
