Recombination and chromosome structure in eukaryotes

Abstract
Allelic recombination frequency and pattern in fungi show strong gene-to-gene variation. At least in two fungal species, Neurospora and Schizophyllum, recombination frequencies in certain chromosomal segments are genetically determined. The possibility that chromosomal proteins and/or synaptinemal complexes may play an important role in regulation of recombination frequency and pattern is discussed.
