Translocation Normal appearing homozygous and heterozygous plants. Heterozygotes with normal have abnormal meiotic configurations with homologous pairing tying affected chromosomes together; results in 50% defective gametes (semisterile ears & pollen).

Translocation Reciprocal Translocation; pollen: Unstained pollen from a heterozygote for T6-9b showing 50% defective pollen grains.

Translocation Reciprocal Translocation: Pollen of a plant heterozygous for TB-9Sb wx stained with I2-KI to show semi sterility assortment of wx1 pollen abortion.

Translocation Reciprocal Translocation: microphoto showing a pollen mother cell of a heterozygote for T8-10 reciprocal translocation (Rhoades 1950)
