From: QTL global meta-analysis: are trait determining genes clustered?

Grouping QTL into non-redundant regions. QTL were grouped into 'non-redundant' QTL regions by combining QTL length overlaps into single contiguous regions. The figure illustrates a sample of Growth QTL category QTL being combined to generate a non-redundant region. Non-QTL regions contain no QTL whatsoever.
