Estimation of Preferential Pairing Rates in Second-Generation Autotetraploid Pacific Oysters ( Crassostrea gigas)

Abstract 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....

Description
Summary:Abstract 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 variation in standing populations may play a role in meiotic mechanisms of polyploids derived from these populations.
