Meiotic Analysis of One Copy of Chromosome sDic-15.

Examination of meiotic chromosome behavior of maize sDic-15 in pollen mother cells. ZmBs sequences are labeled in magenta, and CRM is labeled in green. Arrows point to the sDic-15 chromosome. Bars = 10 μm.

(A) Diakinesis.

(B) Metaphase I. sDic-15 has moved to the plate with the other bivalents.

(C) Anaphase I. sDic-15 has moved to one pole randomly.

(D) Early prophase II. sDic-15 still stays at one pole.

(E) Metaphase II. sDic-15 has moved to the plate with the other chromosome.

(F) Tetrad. sDic-15 sister chromatids are separated to the two poles.
