From heterosis to outbreeding depression: genotype-by-environment interaction shifts hybrid fitness in opposite directions 

Wang, Haolong; Su, Baofeng; Zhang, Ying; Shang, Mei; Li, Shangjia; Xing, De; Wang, Jinhai; Bern, Logan; Johnson, Andrew; Al-Armanazi, Jacob; Hasin, Tasnuba; Hettiarachchi, Darshika; Parrales, Abel Paladines; Dilawar, Hamza; Bruce, Timothy J; Dunham, Rex A; Wang, Xu; 0000-0002-7594-5004 (2024-05-19)
In F1 hybrids, phenotypic values are expected to be near the parental means under additive effects or close to one parent under dominance. However, F1 traits can fall outside the parental range, and outbreeding depression ...

Identification of transcriptome markers in blue catfish cryopreserved sperm to predict male reproductive performance for catfish aquaculture 

Zhang, Ying; Wood, Kyle R; Dunkleberger, Thu M; Martin, Kaylan A; Roy, Luke A; Dunham, Rex A; Butts, Ian AE; Wang, Xu; 0000-0002-7594-5004 (2025-05-08)
In hybrid catfish aquaculture, hatch success varies significantly using cryopreserved sperm from different males, but current phenotypic assays only explain a fraction of observed variations. We profiled the sperm transcriptome ...
