Excess heterozygosity contributes to genetic map expansion in pea recombinant inbred populations.

Several plant genetic maps presented in the literature are longer than expected from cytogenetic data. Here we compare F(2) and RI maps derived from a cross between the same two parental lines and show that excess heterozygosity contributes to map inflation. These maps have been constructed using a common set of dominant markers. Although not generally regarded as informative for F(2) mapping, ...

Resolution of Genetic Map Expansion Caused by Excess Heterozygosity in Plant Recombinant Inbred Populations

Recombinant inbred populations of many plant species exhibit more heterozygosity than expected under the Mendelian model of segregation. This segregation distortion causes the overestimation of recombination frequencies and consequent genetic map expansion. Here we build upon existing genetic models of differential zygotic viability to model a heterozygote fitness term and calculate expected ge...

The map expansion obtained with recombinant inbred strains and intermated recombinant inbred populations for finite generation designs.

The generation of special crosses between different inbred lines such as recombinant inbred strains (RIS) and intermated recombinant inbred populations (IRIP) is being used to improve the power of QTL detection techniques, in particular fine mapping. These approaches acknowledge the fact that recombination of linked loci increases with every generation, caused by the accumulation of crossovers ...

Genetic dissection of intermated recombinant inbred lines using a new genetic map of maize.

A new genetic map of maize, ISU-IBM Map4, that integrates 2029 existing markers with 1329 new indel polymorphism (IDP) markers has been developed using intermated recombinant inbred lines (IRILs) from the intermated B73xMo17 (IBM) population. The website http://magi.plantgenomics.iastate.edu provides access to IDP primer sequences, sequences from which IDP primers were designed, optimized marke...
