Estimation of preferential pairing rates in second-generation autotetraploid pacific oysters (Crassostrea gigas).

Abstract excerpt

Although previously disregarded, polyploidy, and in particular autopolyploidy, is now believed to have played a prominent role in the evolution of plants and animals. We estimated the rate of preferential pairing in second-generation autotetraploid Pacific oysters from gametic frequencies. We found significant levels of preferential pairing in these recently generated autopolyploids, suggesting that genetic...
