[Multi-oocytic follicles in 2 related female hamsters and an in vitro study of their meiosis. A possible explanation of heriditary twinning].
Multi-oocytic follicles containing 2 to 6 oocytes were observed in two female hamsters, a mother and daughter pair. Cultivation rarely permitted more than one oocyte to reach maturation. These findings, which could explain the hereditary character of dizygotic twinning, are compared with observations made in other mammalian species.
