We present a generally applicable method allowing rapid identification of causal alleles in mutagenized genomes by next-generation sequencing. Currently used approaches rely on recovering homozygotes or extensive backcrossing. In contrast, SNP-ratio mapping allows rapid cloning of lethal and/or poorly transmitted mutations and second-site modifiers, which are often in complex genetic/transgenic backgrounds.
