Exploring genetic variation in thermal tolerance in the temperate anemone, Anthopleura elegantissima. Anthopleura elegantissima

We collected over 500 anemones across 60 genotypes from the Oregon coast and subjected individuals to either control (12°C) or heat-stress conditions (23°C) for two weeks. We profiled transcriptional responses in anemones with contrasting phenotypes, estimated clonal repeatability and narrow-sense heritability using SNP genotyping, and tested for associations between thermal tolerance phenotypes and genotypes by conducting a genome wide association study.
