Abstract

Analysis of maize F2 plants revealed a decrease in the recombination fraction (rf) between the marker loci in case of heterozygosity of adjacent chromosomal regions. The relative decrease in rf was positively associated with the length of the heterozygous region. Heterozygosity had no effect onrfin other chromosomes. These results can be explained by defective pairing of heterozygous chromosomal regions in meiosis.
