You are conducting genetic linkage studies of an autosomal recessive disease whose chromosomal location has not been firmly established. You are focused on two SSR markers that may be linked to each other and to the disease. Here are two families in which some individuals are affected:

                             

Calculate LOD scores for linkage at θ= 0.02 between the disease and SSR42 in Family 2.
