Comparison of segregation analysis and map length estimation using FISH and meiotic MI chromosomes

CriteriaSegregation analysisGenetic map length estimation using FISH and MI configurations
Recombination processesReciprocal genetic exchange and gene conversion eventsReciprocal genetic exchange
Resolution of recombination eventsMultiple interval estimates along chromosome armNo interval estimates; chromosome arm estimate
Map functionKosambi (1944)Carter and Falconer (1951)
BiasSelective recovery bias resulting from gametic or zygotic selectionNo selective recovery bias; analysis performed before gametogenesis
Sampling100–200 progeny>200 cells per plant
