TL;DR: The results suggest that biological function of setdm might be related to testis development and spermatogenesis of gibel carp, and it is proposed that the novel male-specific setdm on extra microchromosomes might be functional divergence gene of the gonad- specific setdmf.

TL;DR: A male-biased mutant family was discovered from the gynogenetic gibel carp, and a male-specific SCAR marker was identified from the mutant family and confirmed to be steadily transmitted to the next generation and consistently detected only in males.

TL;DR: The results suggest that the incorporated sperm-derived DNA fragments by allogynogenesis should increase genetic diversity and introduce new traits into unisexual animals which will benefit genetic breeding of gibel carp.

TL;DR: This study develops an optimal method for artificial gynogenesis, through which the male heterogametic XX/XY sex determination system was revealed in Lanzhou catfish and directly obtains YY males for future production of all-male population in aquaculture.

TL;DR: Zhang et al. as discussed by the authors identified a massively expanded satellite DNA cluster on microchromosomes of hexaploid gibel carp via comparing with the ancestral tetraploid crucian carp (Carassius auratus).
