#Unit 8. Inheritance Biology
Conjugation allowed between Hfr with genotype A B C D E and F- with genotype a b c d e. At regular intervals, a sample of cells was removed and agitated
vigorously in a kitchen blender to halt all conjugation and DNA transfer. After interrupted conjugation, ex-conjugate were selected on minimal media at regular interval and find different number of ex-conjugate?
abCde - 10, abCdE - 30 , aBCdE - 40 , ABCdE - 20 , ABCDE - 50

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:
