Summary
Alleles are expected to be non-randomly distributed among rearranged chromosomal segments sheltered from recombination. Linkage analysis was carried out on 57 genomes representing 20 populations of the permanent translocation heterozygote, Oenothera laciniata, to determine the distribution of alleles among chromosomal complexes. For any given Pgi-1 heterozygote analysed, allelic inheritance was uniform and specific to each complex both among sibs and over the genomes tested. Certain developmental characters, manifested in hybrids with the related O. grandis, were also strongly associated with certain complexes; however, no other morphological characters, vegetative or floral, were found to be associated with either complex.
