This book deals with the various practical problems on concepts based on Mendalian genetics such as monohybrid cross, incompletely dominant genes, lethal genes, dihybrid cross, heterosis in fish breeding, sex determination, inbreeding and effective breeding number, selection and heritability and gene and genotype frequency are given with solution and answers. It is also provides detailed protocol with explanation is also given for induction of Triploidy in fishes, Induction of Gynogenesis in fishes, Preparation of metaphase chromosomes from fish tissues, chromosome preparation from embryos, Cryopreservation of fish sperm and checking the fish sperm motility.
