Background Sex chromosomes evolve from autosomes and are expected to be initially homomorphic, though they may become heteromorphic over time. In diploid systems, one sex chromosome often degenerates,...

Characterizing genetic variation in natural populations is vital to evolutionary biology; however, many non-model species lack genomic resources. Here…

Bryophytes are a widespread group of land plants that occupy nearly all biomes, yet their genetics and evolutionary history have long remained underexplored. Now, a study that generates extensive geno...
