When a scientist is attempting to use haplotype analysis to link a disease-causing allele to a molecular marker, it is important for the marker to be close to the disease-causing allele, otherwise ________ may occur.

Question

Quizplus · Accepted Answer

Crossing over is more likely to occur between two genes the further apart they are on a chromosome, which can disrupt the association between a disease-causing allele and a molecular marker if they are not closely linked. This makes it harder to use haplotype analysis for linking the disease-causing allele to the marker.
