which best explains what happens during crossing over?\nthe chromosomes have electrical connections that allow them to line up randomly.\npaired chromosomes overlap and portions of dna switch between chromosome.\ngenetic material is switched because the chromosomes line up independently.\nchromosomes line up randomly and cross genetic information between unpaired chromosomes.

Answer

Brief Explanations:

Crossing - over occurs during meiosis when homologous (paired) chromosomes overlap and exchange segments of DNA. This process increases genetic diversity. The other options are incorrect as they do not accurately describe the mechanism of crossing - over.

Answer:

Paired chromosomes overlap and portions of DNA switch between chromosome.
