This paper introduces two new methods for gene discovery using conditional genome-wide associations and validates three novel genes affecting flowering time in Arabidopsis.

The paper simulates evolution in diploid and autotetraploid populations to show that pseudo-overdominance is more common in polyploids due to reduced recombination and increased masking of deleterious mutations.

This study uses simulations to show that autopolyploids face greater fitness costs during range expansion than diploids, while allopolyploids with disomic inheritance are shielded, and range expansion accelerates diploidization in autotetraploids.

The paper investigates the evolutionary history of North American gray treefrogs using genomic data to show that H. versicolor arose from autopolyploidization and that hybridization between diploids and tetraploids has led to re-formed polyploid lineages.
