During meiosis, what are the gametic consequences of a paracentric inversion with a single crossover event, compared to a pericentric inversion with a single crossover?
What will be an ideal response?
The paracentric inversion results in two viable gametes: one with a normal chromosome and one with an inversion chromosome. Two gametes will contain fragments of a broken dicentric chromosome and will be inviable (since the acentric fragment is lost). The pericentric inversion also results in two viable gametes–one containing a normal chromosome and one containing an inversion chromosome–and two inviable gametes containing different deletion/duplication products.
