Classical, or constitutive (Brown,1966), heterochromatin was first clearly defined by Heitz (1928), and its biological roles have been debated ever since. Constitutive heterochromatin is defined cytologically - whole chromosomes or chromosome segments which maintain

Generally, during meiosis, each pair of homologues must align, associate closely along their length and crossover at least once; then chiasmata must be maintained until homologues can be directed to opposite poles for the first division anaphase, and s

In many of the larval tissues of Drosophila the cells become quite large; the DNA replicates, but rather than separating, the sister chromatids remain synapsed through several rounds (up to ten) of replication, resulting in large polytene chromosomes which are easily

It is an arduous task to construct a genetic map and their existence is a tribute to the dedication of the geneticists and breeders who have made it their labor. The techniques of molecular biology have recently offered a more rapid approach
