In the Course of Estimating the Degree of Linkage of a Marker

question 25

Multiple Choice

In the course of estimating the degree of linkage of a marker and a quantitative trait of interest,researchers announced that they obtained a LOD score of 4.5.This finding indicates that:

• B)the marker is 4.5 map units away from the QTL controlling the trait of interest.
• C)the marker is most likely not linked to the QTL controlling the trait of interest.
• D)the odds that the marker is linked to the QTL controlling the trait of interest are 4.5:1.
• E)the odds that the marker is linked to the QTL controlling the trait of interest are 4500:1.
