Co-linearity of Drosophila X-chromosome polytene banding and its genetic map

Genetic maps (top) show that the distances derived from genetic crosses correlate very well with the physical order and distances among loci inferred from their positions in the polytene chromosomes (bottom). The genetic and physical maps are therefore described as co-linear.
