Triploidy in mollusks (specimens with three pares of chromosomes instead of two) has been commercially developed in the US since the ‘80s, when the first studies were made in oysters. At the beginning this technique was performed with exogenous or chemical stimuli, which resulted in 60% to 80% triploidy.

Later on a group of U.S. researchers made up of doctors—specialists in mollusk genetics— Stan Allen and Ximing Guo, made a qualitative leap forward by generating tetraploid oysters (4n), a significant advance that permitted developing genetic triploid seeds by crossing them with normal or diploid organisms. Thus, and thanks to the new genetic procedure, the descent of up to 99.9% of triploid animals became a reality.
