Unit II: 
Chromosomal variations

Chromosomal aberrations, duplication, deficiency, inversion and translocation, changes in chromosome number: haploids, aneuploids and polyploids, autopolyploids and allopolyploids, monosomics and trisomics. Mutations- spontaneous and induced, physical and chemical mutagens , related genetic disorders- Turner’s syndrome, Down’s syndrome, Kleinfelter’s syndrome, Cri-du –chat syndrome, Triple X syndrome.

Unit III: 
Gene expression

Gene fine structure, introns and their role in genetics,  regulation of  gene expression in prokaryotes and eukaryotes, lac operon and tryptophan operon, lytic and lysogenic cycle in bacteriophages.

                                                                                                                                                                                    

 

                                                                               

                                                                                                                                                                                                

Unit IV: 
Extra nuclear genome

 Genetics of mitochondrial and chloroplast DNA- structure, functions and inheritance, plasmids and episomes; maternal effects and cytoplasmic inheritance, cytoplasmic male sterility.         

Unit V: 
Plant Breeding

 Methods of plant breeding, selection (mass, pureline and clonal), pedigree analysis, acclimatization, hybridization, heterosis and inbreeding depression
