The upper most following figure above shows the locations of four genes on the genetic map of an organism; the lower figure shows the locations of the same four genes on a physical map derived from the nucleotide sequence of the DNA of that organism. The maps are not identical because

#SCPH06 I Botany

There is no relationship between the position of genes in a genetic map and their positions on the DNA
recombination frequencies per kb of DNA are not uniform throughout a chromosome
the farther apart two genes are, the more likely they are to recombine
some genes contain introns

The diagram below shows the F factor and a portion of the E. coli chromosome that has three different insertion sequences (IS) of the same type as is carried on F.

Describe the three different Hfrs (Hfr #1, Hfr #2 and Hfr #3) that can be formed by recombination between the IS on F and each of the IS sequences on the chromosome. Some including the positions of each of the markers (A, B, C, and D) and state which of these markers would be transferred early?
