|a Monosomics lack a pairing partner in each meiotic cell, and genes on an entire chromosome are present in the hemizygous condition. Monosomics for chromosomes 1, 2, 3, 4, 6, 7, 8, 9, and 10 in Zea mays have been isolated. This is the only series of this type that has been recovered in any diploid organism. The monosomic plants are vigorous, good cytological samples can be taken, and crosses can be made. All possible monosomic types are being isolated and characterized by studying: (1) the cytology of meiosis; (2) the cytological behavior of univalent chromosomes; (3) the effect of monosomy and trisomy on intergenic and intragenic recombination; (4) the frequency and types of spontaneous chromosomal aberrations arising in monosomics; (5) the effect of aneuploidy on the relative amounts of specific fatty acids in embryos; (6) monosomic mutational mapping; and (7) metabolic profile analysis of monosomics. Systems in maize to detect the environmental and genetic induction of non-disjunction are also being developed. By comparing a monosomic with its disomic siblings, one compares one and two copies of all genes on an entire chromosome. If a gene expressing dosage effects resides on a specific chromosome, a difference will be found between a plant monosomic for that chromosome and its diploid siblings. Genetic factors that control the meiotic process, genetic recombination, lipid biosynthesis, and the free amino acid pool have been discovered.
