To discuss the important topics under genetics and breeding since a knowledge of genetics and breeding is essential for fishery science
Have an enhanced knowledge of fish genetics and breeding
Understand how genetic manipulations affect fish breeding
Principles of genetics and breeding, Gene and chromosome as basis of inheritance, Mendel’s
law of inheritance – complete and incomplete dominance, monohybrid and dihybrid ratios.
Gene interactions – dominant and recessive epistasis. Pleiotropism. Lethal genes. Mutation.
Sex - linked genes, sex influenced and sex limited traits. Linkage and crossing over.
Introduction to population genetics. Hardy- Weinberg law and its significance. Chromosomal
structure and aberrations. Chromosome manipulation techniques - androgenesis, gynogenesis
and polyploidy and identification of ploidy. Sex determination. Cross breeding (hybridization)
– types of cross breeding, heterosis and design of cross breeding programmes, hybridization in
different fishes. Quantitative genetics – quantitative traits, polygenic traits, heritability.
History and present status of selective breeding programs in aquaculture. Selection methods
and mating designs. Design for selective breeding. Inbreeding and its consequences.
Domestication methods. Seed certification and quarantine procedures. Cryopreservation of
Problems on Mendelian inheritance (qualitative genetics) - monohybrid and
dihybrid ratios and epistasis. Problems on quantitative traits, response to selection and
heritability. Estimation of rate of inbreeding and heterosis. Mitotic and meiotic chromosome
preparation. Demonstration of protocol of androgenesis, gynogenesis and polyploidy.
Problems on gene and genotypic frequency. Gamete cryopreservation protocols and quality
evaluation of fish milt.
