WebbShape of metacentric chromosome in anaphase is A L-shaped B V-shaped C J-shaped D I-shaped. Medium Solution Verified by Toppr Correct option is B) Metacentric … WebbChromosome shape is usually observed during anaphase. The shape of chromosomes is determined by the position of centromere, a part of chromosome on which spindle fibres are attached during metaphase. Chromosomes have generally three different shapes, viz., rod shape, J shape and V shape.

WebbIn anaphase I, the homologues are pulled apart and move apart to opposite ends of the cell. The sister chromatids of each chromosome, however, remain attached to one another and don't come apart. Finally, in telophase I, the chromosomes arrive at … WebbIn anaphase I of meiosis I the homologous chromosomes are pulled apart from each other. The homologs are cleaved by the enzyme separase to release the cohesin that held the homologous chromosome arms together. [7] This allows the chiasmata to release and the homologs to move to opposite poles of the cell. [7] software house international uk
