Answer:

Chromosomes can swap segments of genes!

The idea that chromosomes can swap parts of genes best explains why crossing over during meiosis results in genetic variation in a population.

The biological process of crossing over occurs during prophase I of meiosis when genetic material is transferred across non-sister chromatids of homologous chromosomes. By giving offspring distinct chromosomes from their parents, chromosomal crossing enhances genetic variety. Because natural selection depends on various alleles to increase or reduce their frequencies, the level of genetic diversity in a population is crucial. A population bottleneck or a disease epidemic are examples of catastrophic genetic and physical events that could wipe out homogeneous communities with little genetic variation.
