The vision of Typhoon Lengkieki

Abstract

Around 1775, Typhoon Lengkieki decimated the population in the Micronesian Pingelap Atoll, leaving only a handful of survivors to repopulate the islands. Their ancestors have a high incidence of the autosomal recessive disorder achromatopsia, or total colorblindness, and genetic analysis of the Pingelapese has revealed the mutation responsible.
