Will mark brainliest and worth 25 ! explain the relationship between crossing over and genetic variation.

Crossing over is termed as a process by which genetic materials are exchanged by non-sister chromatids during meiosis.

Crossing over results in the new combination of information in genetic for, the cell for a specific trait.

 It ensures that organisms are identical from one generation to another. Genetic recombination allows variations in genetic materials which are passed through generations.
