Objective: 

To study the Mendelian as well as modern aspects of genetics with Plant Breeding.

 

Unit I: 
Genetic Inheritance

 Mendelism, laws of inheritance, Gene interactions: allelic and non allelic; linkage and crossing over, multiple alleles, sex determination, sex linked, sex influenced, sex limited traits.

 

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- muton, recon, cistron, introns and their role in genetics,  regulation of  gene expression in prokaryotes: lac operon and tryptophan operon, regulation of  gene expression in  eukaryotes: multigene families, histone modification, chromatin remodeling, DNA methylation, enhancers, alternate splicing , lytic and lysogenic cycle in bacteriophages.

 

Unit IV: 
Extra nuclear genome

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

 

 

Unit V: 
Plant Breeding

Introduction to plant breeding: Plant introduction, acclimatization domestication and plant quarantine; Methods of plant breeding; selection - mass, pureline and clonal, pedigree analysis, hybridization, heterosis and inbreeding depression
