Allochrony in Atlantic Lumpfish

Allochrony is a form of reproductive isolation characterized by differences in the timing of spawning and may play a crucial role in the genetic and phenotypic divergence within species. The Atlantic lumpfish () is known to spawn in spring and autumn. However, the role of allochrony on the genomic s...

The Atlantic lumpfish () is known to spawn in spring and autumn. However, the role of allochrony on the genomic structure of this species has not been addressed.
