When homologous chromosomes line up during meiosis and one arm of a chromatid crosses over the arm of another chromatid, this process is known as crossing over or recombination. The result of this event is:
**additional variation in the DNA combination of each sex cell formed.**
Crossing over allows for the exchange of genetic material between homologous chromosomes, leading to new combinations of alleles in the resulting gametes. This increased genetic diversity is a key feature of sexual reproduction.
