If the distance between the genes A,B,C on the chromosomes is as follows.Prepare a genetic map assigning the correct order of genes.Which of the genes pairs will show maximum frequency of crossing over ?A=5cm,B-C=3cm,A-C=2cm.

A= 5 cm, it should be actually AB= 5 cm
AC= 2cm
BC= 3 cm
The genetic map of the genes A, B and C can be depicted as under:
The AB pair of genes will shown maximum frequency of crossing over as the frequency of crossing over increases with the increase in distance. This is due to the reason that genes which are closely located are strongly linked and thus show less crossing over.

A-C shows max crossing over as the distance between them is min and can easily form chaismata

@ Vibha wat about the genetic map?
