Crossing over is often reduced around centromeric regions of chromosomes. If you were trying to construct a genetic map of two linked marker loci in this region, what result might you obtain and why? How would the genetic map correspond to the physical map?

If we try to construct a genetic map of two linked marker loci in the centromeric regions then we find that there will be low recombination frequencies. Through this pattern we can draw a relation between the genetic map with its physical map that the markers are quite close to one another.

Explanation:

a physical change is being made.
