He meant which side of the species carries each mutation forward, in his account. Ra taught that the dropping of the larynx, the mutation in Gate 12 some 85,000 years ago that made articulate language possible, was carried by the female and passed to every child. For the Gate 55 mutation he said the opposite: he was told it is carried through the male. When he explains the codons, he ties this to the histidine chemistry in the male prostate, and says that in the wrong time frame the same chemistry shows up as disease instead of as a mutated child. That is where his much quoted claims about prostate disease come from. Please hold all of this as Ra's cosmology, not as a fact or a medical statement. It is not a promise of anything and nobody knows exactly how it will unfold. For anything about your own health, or a partner's, please talk to a doctor.
This is not a fact, not medical advice and not a promise of healing. It is part of the cosmology Ra Uru Hu, who founded Human Design, left behind, and nobody knows exactly how it will unfold.
