In vertebrates, mainly single genes with an allele ratio of 1: 1 trigger sex-determination (SD),
leading to initial equal sex-ratios. Such genes are designated master-key regulators (MKRs) …

The impact of sex chromosomes and their turnover in speciation remains a subject of
ongoing debate in the field of evolutionary biology. Fishes are the largest group of …

Tilapia growth and sex are key traits for aquaculture. Elucidating their molecular
mechanisms can enable molecular breeding and accelerate genetic gain. To uncover the …

Abstract The Nile tilapia (Oreochromis niloticus), with a system of XX/XY sex determination,
is a worldwide farmed fish with a shorter sexual maturation time than that of most cultured …

Background Interspecies hybridization is an important breeding method to generate fishes
with heterosis in aquaculture. Using this method, hybrid Nile tilapia (Oreochromis …

Aquaculture is one of the fastest growing agro‐food industries in the world and Asia
dominates the world's fish production (70% of total) with a high potential to ensure global …

Advances in genome sequencing have greatly accelerated the identification of sex
chromosomes in a variety of species. Many of these species have experienced structural …

Nile tilapia display conspicuous differences in growth rates between genders, as males tend
to outpace and outgrow females. The production of all male Nile tilapia populations using …
