Prerequisite	Type	Confidence	Evidence level	Note	Sources
Genetics (Mendel) (genetics_mendel)	required	88%	textbook	The node is scoped to genetics-informed plant breeding; Mendel's laws and their 1900 rediscovery are the direct inheritance framework.	1900: Rediscovery of Mendel's Work (National Human Genome Research Institute, 2013, official_agency) • Supports: node, edge
Agriculture (agriculture)	historical_predecessor	75%	textbook	Domestication, selection, and crop cultivation are the long-running agricultural substrate on which scientific plant breeding built.
