Meiosis refers primarily to the cell division for reproduction. Meiosis, the procedure of producing gametes in preparation for sexual reproduction, has long been a focal point of concentrated research. It has been researched at the cytological, hereditary, molecular and cellular stages. Researches in model systems have exposed universal essential mechanisms while parallel studies in various organisms have led to the discovery of variations in meiotic methods. This book primarily focuses on the molecular and comparative study of meiosis via model systems. It collects various strands of examination into this enthralling and demanding field of biology.
