International Series of Monographs on Pure and Applied Biology, Volume 10: Oogenesis: The Storage of Developmental Information focuses on the processes, reactions, and transformations involved in oogenesis. The book first offers information on embryonic development as a communication problem, formation of the egg cells, and the egg nucleus during oogenesis. Topics include decoding of developmental information, egg membranes, oogenesis, phase of nuclear activity, cytochemistry of the nucleus, and the egg cell. The manuscript also ponders on the cytoplasm and its inclusions and the relationships between the egg cell and the auxiliary cells. The text elaborates on the metabolism of the oocyte, cortex, and polarity and symmetry. The book also examines the storage of developmental information and information theory and biology. Genotypical information, physical foundation of developmental biology, and information and finality are discussed. The manuscript is a dependable reference for readers interested in oogenesis.
