2002–2009 — The first major offshoot: the Gene Keys
Richard Rudd, who founded and led the Human Design school in the United Kingdom from 1997 until Richard Beaumont's contractual appointment as UK director in July 2004, began synthesizing what became the Gene Keys around 2002 and published the foundational book in 2009. The Gene Keys use the same sixty-four I Ching hexagrams as Human Design's gates — each Gene Key number matches the corresponding gate number exactly — recast from energetic mechanics toward contemplative inner work through a model of Shadow, Gift, and Siddhi frequencies. Gene Keys Ltd. describes the relationship as a lineage one, not an opposition.
