Practice questions testing deep understanding of mitosis, meiosis, and crossing over.
Q1. During the Pachytene stage of Prophase-I in Meiosis, a phenomenon called 'Crossing Over' occurs between homologous chromosomes. Explain the biological mechanism of this event and its critical importance to the survival of a species over millions of years.
Q2. Cancer is often described fundamentally as a disease of the cell cycle. Biologically, what specifically goes wrong with the cell cycle to cause a cancerous tumor to form?
Q3. Assertion (A): In Meiosis II, the number of chromosomes is reduced by half. Reason (R): Meiosis II is a reductional division designed to halve the genetic material for gamete production.
