How do different strains of E.coli can reveal different linkage arrangements of genes in Hfr crosses?
A)They do not.All Hfr strains are identical.
B)Different strains may have different F factors and therefore different initiation points for chromosome transfer.
C)Hfr strains will demonstrate different areas of recombination,due to dominance and recessiveness of genes.
D)In different Hfr strains,different genes will be transferred based on where the centromere resides.
E)In different Hfr strains,genes can be in different order on the chromosome.

Question

Quizplus · Accepted Answer

Different strains of E.coli can have different F factors integrated at various points in the chromosome, leading to different initiation points for chromosome transfer during Hfr conjugation. This results in different linkage arrangements of genes being revealed.
