The Queensland Rothmans Medal was also last awarded in 1996, as the Queensland Cup superseded the Brisbane Rugby League as Queensland's premier rugby league competition in 1997. The Dally M Medal was named after Henry Herbert 'Dally' Messenger, who was instrumental in the establishment of rugby league football
Dally (gene) is essential for a normal biosynthesis of dally. That is why the absence or malfunction of this enzyme doesn’t allow the correct Wg and Dpp signalling. Also the expression of mutated dally proteins alters Wnt signalling pathways, which leads to anomalies in Drosophila melanogaster’s eye, antennal, genital, wing and neural morphogenesis. Dally's gene was located in the chromosome 3, concretely in the region 3L 8820605-8884292. The mutation of Dally is a consequence of the P-element and the place where it is located. It is possible to differentiate between the mutants Dally-P1 and Dally-P2, depending on where the insertion of P-element
