Abstract
Meiosis and fertilization in spawned eggs of the American oyster, Crassostrea virginica, are of the normal type found in the large majority of the metazoa and higher plants. Various deviations from the regular sequence of these events were not infrequent, however, in oyster eggs examined in this study. Meiosis and fertilization can be cytogenetically followed critically in these eggs, which, consequently, offer many opportunities for experimental manipulation of the genetic material.
