Extended Data Fig. 1: Genome-wide distribution of LOH and introgressions.
From: A yeast living ancestor reveals the origin of genomic introgressions
a, Genotype maps of the genome of the living ancestor (top) and the 17 Alpechins. The DNA of the living ancestor is coloured to denote S. cerevisiae (blue) and S. paradoxus (red) DNA, respectively. The DNA of the Alpechins is coloured to denote the S. cerevisiae background (blue) and the interspersed introgressions that are homozygous (red) or heterozygous (grey) for S. paradoxus DNA. There is extensive overlap between the positions of S. paradoxus LOH in the living ancestor and introgressions in the Alpechins. b, Magnified view of chromosome II. Colours as in a. White circles indicate centromeres. Genomic coordinates are based on the S. cerevisiae DBVPG6765 genome assembly.
