Evolution of Bird Sex Chromosomes Narrated by Repetitive Sequences: Unusual W Chromosome Enlargement in Gallinula melanops (Aves: Gruiformes: Rallidae).

abstract：:RNA interference (RNAi) refers to the selective degradation of mRNA induced by double-stranded RNA (dsRNA), first discovered in Caenorhabditis elegans. Homology-dependent silencing phenomena related to RNAi have been observed in many species from all eukaryotic kingdoms. RNAi and related mechanisms share several conse...
