Cytogenetic mapping in maize

Abstract
Cytogenetic maps depict the location and order of markers along chromosomes. Cytogenetic maps are important in genome research as they relate the genetic data and molecular sequences to the morphological features of chromosomes. In this paper, we discuss various methods used in cytogenetic mapping in maize, with special reference to fluorescence in situ hybridization (FISH) of single-copy sequences on meiotic pachytene chromosomes.
