Genetic dissection of FLO8-independent glucose-only invasion. (A) Genome-wide relative allele frequency plot of glucose-only FLO8^BY BYxYJM segregants. FLO8 and the markers used to generate haploid progeny are highlighted by red vertical bars, while the strongly enriched locus on chromosome VIII, which was nearly fixed for the BY allele, is highlighted by a green vertical bar. The genomic interval underlying the chromosome VIII peak is also provided. (B) Comparison of Segregant 1, a glucose-only FLO8^BY individual, and the GPA1^YJM Segregant 1 supports GPA1 as the causal gene underlying the chromosome VIII locus.
