Genetic Mapping of Thermotolerance Differences Between Species of Saccharomyces Yeast via Genome-Wide Reciprocal Hemizygosity Analysis

Overview

This article presents a novel method called reciprocal hemizygosity via sequencing (RH-seq) to map genetic differences between species. The technique allows for high-throughput analysis of trait differences by tracking the fitness of hemizygotes generated through transposon mutagenesis.
