Genetics-Solved Problem from Bacterial Genetic Recombination

Dr CharuSudan


Question: A co-transduction experiment was performed to decipher the linear order of 4 genes: w, x, y and z. Three sets of experiments were performed. In set 1, the Transductants were selected for gene w, in set 2, gene x was selected and in set-3, gene y was selected. In each set, the transductants were screened for co- transduction of the other markers.
Based on the frequencies of co-transduction,  identify the most likely order in the genome.                                                                          

1. w, x, y, z     2. x y z w         3. y z w x         4. w z x y


                                                                                     Based on question from CSIR-NET (2014) 
For answer and analysis
