[HTML][HTML] Homeology of sex chromosomes in Amazonian Harttia armored catfishes supports the X-fission hypothesis for the X1X2Y sex chromosome system origin
The Neotropical monophyletic catfish genus Harttia represents an excellent model to study

Recent evolution of a maternally acting sex-determining supergene in a fly with single-sex broods
Sex determination is a key developmental process, yet it is remarkably variable across the
tree of life. The dipteran family Sciaridae exhibits one of the most unusual sex determination …

Genomic evidence reveals three W-autosome fusions in Heliconius butterflies
Sex chromosomes are evolutionarily labile in many animals and sometimes fuse with
autosomes, creating so-called neo-sex chromosomes. Fusions between sex chromosomes …
