maize mutant phenotypes

reciprocal translocation pollen: Normal appearing homozygous and heterozygous plants. Heterozygotes with normal have abnormal meiotic chromosome configurations with homologous pairing tying affected chromosomes together; results in 50% defective gametes (semisterile ears & pollen). Photo of unstained pollen from a heterozygote for T6-9b showing 50% defective pollen grains.
