This chapter examines the circumstances and opportunities in which maize genetics research was founded, its role in establishing and spreading genetics widely, and its influence on cooperative sharing of information and data among investigators.

EMS also generates half-plant chimeras, which have interesting consequences for lethal dominant mutations. Although dominant mutants are often consid

The chromosomes at this stage are not as condensed as in somatic cells and have many distinguishing characteristics such as knob heterochromatin, chromomere patterns and arm ratios that permit each member of the karyotype to be identified.

At the gene level, single nucleotide polymorphisms are common, especially in introns and untranslated regions of genes. Depending on choice of experimental population and region in the genome, linkage disequilibrium between polymorph
