Con esta técnica basta una planta y su descendencia para validar un genoma y localizar genes de interés.

Approaches requiring inbred parental lines are particularly difficult to implement in plants with long generation times or severe inbreeding depression. We developed haplotype-resolved genetic mapping (HRGM) to construct linkage maps from a single heterozygous individual and its selfed progeny without requiring inbred parental lines. HRGM combines haplotype-resolved unitig assemblies from the S0 parent with genotype data from its S1 progeny, using sequence differences between the two haplotypes to define phased SNP markers.
