Whole-genome analysis across ten songbird families within Sylvioidea reveals a novel autosome–sex chromosome fusion

Hanna Sigeman, Suvi Ponnikas & Bengt Hansson
Sex chromosomes in birds have long been considered to be extremely stable. However, this notion has lately been challenged by findings of independent autosome–sex chromosome fusions within songbirds, several of which occur within a single clade, the superfamily Sylvioidea. To understand what ecological and evolutionary processes drive changes in sex chromosome systems, we need complete descriptions of sex chromosome diversity across taxonomic groups. Here, we characterize the sex chromosome systems across Sylvioidea using whole-genome data...
