What is the co-transduction frequency for the A and B genes, from the following dataset?(Assume that there has been selection for the A+ form of the A gene). Genotype Number

#Unit 8. Inheritance Biology
In a transduction experiment, phage P1 is grown on a bacterial host of genotype A+ B+ C+ and the resulting lysate is used to infect a recipient strain of genotype A– B– C–. The genes are in an order such that B is in the middle, and the distance between A and B is greater than the distance between B and C. Based on this information, which of the following least genotype?

In the mating Hfr met- his+ leu+ trp+ × F- met+ his- leu- trp-. The met marker is known to be transferred very late. After a short time, the mating cells are interrupted and the cell suspensions plated on four different growth media. The amino acids in the growth media and the number of colonies observed on each are as follows:
histidine + tryptophan 250 colonies
histidine + leucine 50 colonies
leucine + tryptophan 500 colonies
histidine 10 colonies

In the mating Hfr Strs met+ his+ leu+ trp+ Ala+ X F- Strres met- his- leu- trp- Ala-. At regular interval time, the mating cells are interrupted and the cell suspensions plated on four different growth media with streptomycin. The amino acids in the growth media and the number of colonies observed on each are as follows:
