2. Based on the figure, the two individuals in which of the following pairs most likely have the greatest genetic similarity across their genomes? A. Individual 3 and Individual 4 B. Individual 12 and Individual 13 C. Individual 16 and Individual 24 D. Individual 18 and Individual 21

B. Individual 12 and Individual 13<br /><br />In a typical pedigree or family tree, individuals who are siblings (such as those with consecutive numbers) tend to have the greatest genetic similarity across their genomes because they share both parents. Therefore, Individual 12 and Individual 13 are likely siblings and would have the greatest genetic similarity.
