Using principal components analysis, the first three independent components accounted over 98% of variations. The first principal component indicated that short arm (SA), arm ratio (AR), intra symmetry chromosomal index (A 1 ) and total form percentage (%TF) were appropriate parameters to classify accessions with 51% of total variations.
The separation of sister chromatids during anaphase is the culmination of mitosis and one of the most strikingly beautiful examples of cellular movement. It consists of two distinct processes: Anaphase A, the movement of chromosomes toward spindle poles via shortening of the connecting fibers, and anaphase B, separation of the two poles from one another via spindle elongation. I focus here on.
