NONRANDOM GENE DISTRIBUTION ON HUMAN CHROMOSOMES
... Human chromosomes are heterogeneous in structure and function. This is the reason for specific banding patterns produced by various chromosome staining techniques. The human genome is a mosaic of isochors and can be partitioned into five families, L1, L2, H1, H2 and H3, characterized by increasing G ...
