Selective Mapping Tutorial


Jose Luis Zambrano Mendoza, The Ohio State University

This selective mapping tutorial, presented in pdf and slideshare formats, introduces selective QTL mapping based on analysis of subsets of a population. The subsets are chosen based on genotype or phenotype. MapPop v. 1.0 software is used to select individuals based on genotype. This tutorial also includes comparison of QTL detection for maize virus resistance based on selective mapping and the whole population.

This selective mapping tutorial:

  • Introduces selective mapping, and why one would want to use it
  • Explains how to perform selective mapping based on phenotype and genotype using MapPop
  • Provides a case study in maize that compares quantitative trait locus (QTL) detection based on all individuals in an F2 mapping population and all marker genotypes and the two selective mapping approaches
