Physical exchange between homologous chromosomes (crossover) occurs during metaphase I of meiosis. true false

False

Explanation:

Crossing over is a phenomenon unique only to the process of meiosis. It is the process whereby a segment of genetic material is exchanged between the non-sister chromatids of homologous chromosome (similar but non-identical chromosomes from both parent).

Crossing over occurs when homologous pairs lie side by side to form a structure called TETRAD in the PROPHASE I stage of meiosis. Hence, according to this question, it is FALSE as crossing over does not occur in the metaphase stage.
