Journal ArticleDOI
Applications of genotyping by sequencing in aquaculture breeding and genetics.
TL;DR: Direct genotyping by sequencing (GBS) techniques have underpinned many of the advances in aquaculture genetics and breeding to date, and have been extensively applied to generate population‐level SNP genotype data.
Journal ArticleDOI
Mapping and validation of the major sex-determining region in Nile tilapia (Oreochromis niloticus L.) Using RAD sequencing.
Christos Palaiokostas,Michaël Bekaert,Mohd Golam Quader Khan,Mohd Golam Quader Khan,John B. Taggart,Karim Gharbi,Brendan McAndrew,David J. Penman +7 more
TL;DR: This study narrows down the region containing the main sex-determining region, and provides genetic markers tightly linked to this locus, with an association that persisted across the population.
Journal ArticleDOI
Mapping the sex determination locus in the Atlantic halibut (Hippoglossus hippoglossus) using RAD sequencing
Christos Palaiokostas,Michaël Bekaert,Andrew Davie,Mairi Cowan,Münevver Oral,John B. Taggart,Karim Gharbi,Brendan McAndrew,David J. Penman,Herve Migaud +9 more
TL;DR: These findings support the hypothesis that the Atlantic halibut has an XX/XY sex determination system and help to speed up the inclusion of neomales derived from many families to maintain a larger effective population size and ensure long-term improvement through selective breeding.
Journal ArticleDOI
A novel sex-determining QTL in Nile tilapia (Oreochromis niloticus)
Christos Palaiokostas,Michaël Bekaert,Mohd Golam Quader Khan,John B. Taggart,Karim Gharbi,Brendan McAndrew,David J. Penman +6 more
TL;DR: Overall, the results from this study suggest that these previously undetected QTLs are involved in sex determination in the Nile tilapia, causing sex reversal (masculinisation) with respect to the XX genotype at the major sex-determining locus in LG 1.
Journal ArticleDOI
Genome-wide association and genomic prediction of resistance to viral nervous necrosis in European sea bass ( Dicentrarchus labrax ) using RAD sequencing
Christos Palaiokostas,Sophie Cariou,Anastasia Bestin,Jean-Sébastien Bruant,Pierrick Haffray,Thierry Morin,Joëlle Cabon,François Allal,Marc Vandeputte,Ross D. Houston +9 more
TL;DR: Tests of genomic prediction suggested that incorporating genome-wide SNP data is likely to result in higher accuracy of estimated breeding values for resistance to VNN, and this study highlights the potential of genomic selection to breed farmed European sea bass with improved resistance toVNN.
