Oyster eggs are arrested before meiosis I and commence after fertilization.
Meiosis is an essential event in the life cycle of all sexually reproducing plants.
Finally, either the chromatids in mitosis or the chromosomes in meiosis I reach the polar state caused by the shrinkage of the spring to its natural length and the diminishing energy of the spring (Figures 1D and 2D).
Halkka (1959) considered the post-reductional meiosis is the most primitive type of meiosis.
The centromeres of each of the two homologous chromosomes paired during the first part of meiosis I are pulled apart and move toward opposite poles of the cell--this occurs in anaphase I.
Dyads from meiosis I united completely and reorganized on a single division plane, except for a few dyads that were separated from the metaphase II division plane - "orphan chromosomes" [ILLUSTRATION FOR FIGURE 1L OMITTED].
The developing meiosis I spindle is oriented with the metaphase plate in the plane of the equatorial cleavage furrows and the poles straddling the mutually perpendicular polar cleavage furrows (Fig.
