The species is diploid, but triploidy occurs naturally in a low but constant frequency. Triploids are also able to be created in labs by blocking meiosis. This triploidy can result in organisms that are larger than their diploid counterparts. The triploid individuals can, at times, create viable progeny (Gong et al., 2004).
The genome of Crassostrea gigas has been investigated in detail, as demonstrated by more than 1700 entries on GenBank (NCBI, 2011). The entire mitochondrial genome has been sequenced (Ren et al., 2010), and patents have been issued. Apparently, the species is used in numerous research projects. For example, possible tumor-reducing agents found in the oysters are being investigated (Wang et al., 2010).
