An amylase gene polymorphism is associated with growth differences in the Pacific cupped oyster Crassostrea gigas
Summary This study investigated the non‐neutrality of genetic polymorphism in two alpha‐amylase genes ( AMYA and AMYB ) in the oyster Crassostrea gigas . Bi‐parental oyster families, bred to be polymorphic for markers in these genes, were monitored for growth and survival for 1 year under standard c...
