Characterization of a meiotic crossover in maize identified by a restriction fragment length polymorphism-based method.

Abstract excerpt

Genetic map lengths do not correlate directly with genome size, suggesting that meiotic recombination is not uniform throughout the genome. Further, the abundance of repeated sequences in plant genomes requires that crossing over is restricted to particular genomic regions. We used a physical mapping approach to identify these regions without the bias introduced by phenotypic selection. This approach is based on...
