This book provides an in-depth exploration of the key concepts in developmental biology, offering a clear understanding of embryonic development. It explains frogs' complex developmental stages, from cleavage to tadpole stages, both externally and internally through diagrams, microscopic and pictorial images of permanent slides. Likewise, the exploration extends to chick embryos, carefully scrutinizing stages categorized by the Hamburger and Hamilton classification, providing information on advanced developmental milestones during incubation times. Moreover, the book provides a firsthand glimpse into the dynamic processes of embryogenesis by demonstrating chick embryo culture from fertilized eggs through pictures and videos. Furthermore, by observing the real time pictures of life cycle and developmental phases of Drosophila, Zebrafish, Caenorhabditis elegans, and Spodoptera litura which are cultivated from stock cultures, readers will obtain important knowledge on genetic and morphological changes. Moreover, detailed sections of the placenta, depicted through photomicrographs and slides, enrich the understanding of mammalian development. This book is a useful resource for both undergraduate and postgraduate students in Life Sciences, as well as for teaching and research. It offers a comprehensive understanding of developmental processes and provides straightforward methods for maintaining model organisms in the laboratory for further exploration.
