BACKGROUND Genetically unreduced (2n) embryo sacs (ES) form in ovules of gametophytic apomicts, the 2n eggs of which develop into embryos parthenogenetically. In many apomicts, 2n ES form precociously during ovule development. Whether meiosis and sexual ES formation also occur precociously in facultative apomicts (capable of apomictic and sexual(More)
Lymphocytes and red cells from various mammalian species have been mixed in vitro in conditions which favor their aggregation in the form of rosettes. The frequencies of rosette formation taken in conjunction with observations on surface bound immunoglobulin on the lymphocytes favor the interpretation that, in many species of animal, rosette formation can(More)
