In the biological practical class, the teacher asked the students to identify the stage of cell division in a slide of runder the objective of a microscope. Some students identified it as of Metaphase of mitosis while other students identificed it as of Metaphse-I of meiosis. Finally, the teacher told the students that it was of Metaphse-I.
