FA215: Induction and Establishment of Tetraploid Oyster Breeding Stocks for Triploid Oyster Production

Figure 1. Schematic diagrams of meiosis in oysters: 1) Diploid production from normal 2N? × 2N?; 2) Triploid production by 2N? × 2N? plus polar body 1 (PB1) or PB2 inhibition, and 3) Tetraploid induction by 3N? × 2N? plus PB1 inhibition.
