This study shows that Vgll3a promotes sexual maturation in Atlantic salmon, with loss-of-function reducing maturation rates in both sexes.

The paper shows that a regime shift in Atlantic salmon populations led to a plastic response bypassing genetic influences on maturation age, despite unchanged allele frequencies.

The paper identifies autosomic pseudocopies of the sdY gene in Atlantic salmon, showing Mendelian inheritance and non-random sex chromosome turnover.
