Figure 2

Difference between plant A and animal B pedigree structure and shape. The plant pedigree in A shows what we have called a pedigree net structure and is more random in shape to a typical human or mammalian pedigree as shown in B where a typical pig pedigree shows a structured pyramidal topology. Sires are coloured blue and dams red with generations running top to bottom. Both diagrams were created using our initial paper-based prototype tool; see “Paper-based pedigree visualization” for more information.
