Figure 2. Case study of genetic variation between three scientists. Left: Schematization of the genetic variation between Drs. James Watson, Craig Venter, and Kim Seong-jin. Colored bars represent genes; different colors represent different alleles, i.e. versions of genes. Some alleles are shared by all three of the men (represented by the dark brown allele that is shared by every person in this image). Besides the universal dark brown allele, Watson and Venter share one other allele (bright blue). However, both share two alleles with Kim (Watson shares red and orange with Kim, Venter shares green and magenta), in addition to the universal allele. Right: There is more similarity between the Kim and Watson and Kim and Venter, than there is between Watson and Venter.
