The Formation of a Novel Intergeneric Hybrid Fish Derived from <i>Megalobrama amblycephala</i> (♀) <i>× Culter dabryi</i> (♂).

ABSTRACT: Distant hybridization in fish serves to integrate the genetic material from two distinct, distantly related species. In this study, we successfully produced a new hybrid fish (BG) through the intergeneric hybridization of blunt snout bream (Megalobrama amblycephala, BSB, 2n = 48, ♀) and green tip culter (Culter dabryi, GTC, 2n = 48, ♂). The objective of this research was to characterize the genetic, morphological, reproductive, and nutritional features of the hybrid compared with its parents. The DNA content and chromosomal number analysis revealed that BG was a diploid hybrid fish with 48 chromosomes. Integrated analysis of 5S rDNA, mitochondrial DNA, and Sox9 gene sequences revealed that BG predominantly inherited its genetic traits from BSB. Notably, certain gene fr
