Locating Recessive Genes to Chromosome Arm with B-A Translocations
The B-A translocations of maize permit recessive genes to be located to the correct chromosome arm in the F1. RFLPs, codominants, and dominant genes with extreme phenotypes when homozygous or hemizygous can also be located to the appropriate chromosome arms by this system. See previous chapter by Carlson for a description of B-A translocation behavior.
