Question

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?

A) The recombination frequencies would be low, and you would deduce that the markers were very close to one another.
B) The recombination frequencies would be low, and you would deduce that the markers were very far from one another.
C) The recombination frequencies would be high, and you would deduce that the markers were very close to one another.
D) The recombination frequencies would be high, and you would deduce that the markers were very far from one another.
E) The recombination frequencies would be too low to detect, and you would not be able to estimate the distance between genetic markers.

Answer 1

A. The recombination frequencies would be low, and you would deduce that the markers were very close to one another.
