Answer» Right option is (c) If gene A has a neighboring gene B, then if an ortholog of A occurs in another genome, the B ortholog is more likely to be a NEIGHBOR of the A ortholog of the genome of the SECOND species if the two species are more DIVERGENT Best explanation: The B ortholog is less likely to be a neighbor of the A ortholog of the genome of the second species if the two species are more divergent. By classifying genes using a nine class functional classification scheme, several genes falling into the same functional CATEGORY are clustered together on the chromosomes of both of these organisms, and the clusters are in a similar order.
