Altered gravitational field effects on the fertilized frog egg

Xenopus laevis and Rana pipiens eggs were centrifuged under various conditions after fertilization. The fertilized egg is most sensitive to altered gravitational fields before first cleavage and abnormalities so induced are typical of the time period of centrifugation. Thus, abnormalities in embryos...

More Information
Summary:Xenopus laevis and Rana pipiens eggs were centrifuged under various conditions after fertilization. The fertilized egg is most sensitive to altered gravitational fields before first cleavage and abnormalities so induced are typical of the time period of centrifugation. Thus, abnormalities in embryos centrifuged at 40 g for 15 min during the first 35 min after fertilization, were confined to a twinning phenomenon.
