NEET Biology question
What is the correct sequence of the steps given here, and which process do they depict? I. Homologous chromosomes move toward opposite poles of the cell; chromatids do not separate. II. Chromosomes gather at the two poles of the cell and the nuclear membranes reform. III. Homologous chromosomes pair and exchange segments. IV. Homologous chromosomes align on a central plate. V. The haploid cells separate completely.
Answer: (A)
Solution
III (pairing and crossing over = zygotene/pachytene) → IV (alignment at the plate = metaphase I) → I (homologues, not chromatids, separate = anaphase I) →
