Answer:
DNA segments are exchanged between two non-sister chromatids during meiosis I.
Explanation:

This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.
