Objective: 

Upon completion of the course the learner will:

CO 31: Understand the different types of gene interactions and predict the outcomes of different genetic crosses.

CO 32: Identify the different types sex determination mechanisms and sex-linked inheritance.

CO 33: Analyse the relationship between linkage and recombination frequencies for mapping.

CO 34: Evaluate the different methods of recombination in prokaryotes

CO 35: Analyse the molecular basis of mutations

CO 36: Understand extrachromosomal inheritance and Hardy Weinberg equilibrium.
