Impact of atrazine on aneuploidy in pacific oysters, Crassostrea gigas
Abstract Aneuploidy has previously been described and studied in the Pacific oyster, Crassostrea gigas , and has been shown to be negatively correlated with growth. The present study investigated the effect of atrazine on the level of aneuploidy in this species. Crassostrea gigas adults and juvenile...
