Crossing Over Is Often Reduced Around Centrometric Regions of Chromosomes

question 48

Multiple Choice

Crossing over is often reduced around centrometric 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?

• 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.
