WebApr 9, 2024 · For example, a crossover event within the loop of a paracentric inversion will lead to a di-centric product that will break into deletion products and produce unbalanced gametes (Figure \(\PageIndex{4}\)). Similarly, with a pericentric inversion, a crossover event leads to duplicate/deletion products that are unbalanced (Figure \(\PageIndex{5}\)).
