Electrophoretic mobility; null allele is known (cold sensitivity); intra/interlocus hybrid bands occur. Genetic 2005 1 coordinates determined from these recombination and map data: adh1 -9- phi1 -5- gdh1; adh1 -11.7- phi1 -4.5- gdh1; see MaizeGDB ID:61819; 9017376. This gene was originally curated in MaizeGDB Database and the map position was displayed on the maize bins map if feasible.
