Why is it essential that genetic markers used in mapping disease genes be polymorphic?
A)If the marker isn't polymorphic,its position cannot be known.
B)If the marker isn't polymorphic,it cannot be physically linked to a gene associated with human disease.
C)If the marker isn't polymorphic,then it will not be inherited in any predictable manner.
D)If the marker isn't polymorphic,then it's impossible to use genetic mapping techniques to establish an association between the marker and the disease gene.
