The paper analyzes gene loss in freshwater sticklebacks using a pangenome approach, finding that demographic factors and selection influence gene presence/absence variation.

The paper tests the drift-barrier hypothesis by analyzing mutation rates in nine-spined stickleback populations, finding a negative correlation between mutation rates and effective population size.

The paper identifies an ongoing sex chromosome turnover in hybridizing stickleback lineages, where younger homomorphic sex chromosomes replace older heteromorphic ones in admixed populations.
