Genetic Inheritance

 Mendelism, laws of inheritance, gene interactions, 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, 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.
