Gametic lethality
Webnovel dwarf gene, d60, together with a gametic lethal gene, gal, in a cross between semidwarf mutant ‘Hokuriku 100’ and its original tall variety ‘Koshihikari’ (Tomita et al., 1989; Tanisaka et al., 1990; Tomita, 1996). The gene d60 was thought to have a unique mode of inheritance that complements the gametic lethal gene, gal. Weband Sandler, 1959). Gametic lethality has also been implicated as a possible cause of anomalous ratios (C. W. Metz, 1929; Gershenson, 1928; Novitski, 1947). How-ever, in these studies where gametic lethality is suggested as a possible cause of abnormal progeny ratios, this has been as a result of eliminating other possibilities
